Digital Manufacturing of Microfluidic Devices (02 May, 2018)

Speaker: Albert Folch

Digital Manufacturing (DM) - of which 3D-Printing is an example - has been applied with great success to improve design efficiency and part performance in the automobile industry, aeronautics, microelectronics, architecture, sportswear, and biomedical implants, among others. However, by comparison with other manufacturing fields, microfluidics has been slow to adopt DM. Microfluidic chips are still designed largely from scratch, the materials (usually thermoset or thermoplastic polymers) are often manually poured into a mold to form 2D-layer replicas, and the mold replicas are manually aligned and bonded to form the final device. The production of microfluidic devices by micromolding, while being optimized for mass manufacturing, cannot be optimized at the same time for design variety. These limitations are difficult for researchers to assimilate because micromolding has been the prevalent mode of microfluidics manufacturing for over two decades. On the other hand, the economics of DM are well-suited for microfluidics because, as opposed to molding approaches, the cost per device does not scale up with its 3D complexity ("complexity is free") and is insensitive to the size of the production batch, i.e. DM is ideal for project customization ("variety is free"). We are developing microfluidic devices through stereolithography (SL), a form of 3D-Printing, in order to make microfluidic technology readily available via the web to biomedical scientists. We have developed microfluidic devices by SL in PEG-DA-based resins with automation and biocompatibility ratings similar to those made with PDMS

Albert Folch received his BSc in physics from the University of Barcelona (UB), Spain, in 1989. In 1994, he received his PhD in surface science and nanotechnology from the UB's Physics Dept. During his PhD he was a visiting scientist from 1990-91at the Lawrence Berkeley Lab working on AFM under Dr. Miquel Salmeron. From 1994-1996, he was a postdoc at MIT developing MEMS under the advice of Martin Schmidt (EECS) and Mark Wrighton (Chemistry). In 1997, he joined the laboratory of Mehmet Toner as a postdoc at Harvard's Center for Engineering in Medicine to apply soft lithographic methods to tissue engineering. He has been at Seattle's UW BioE since June 2000 where he is now a full Professor, accumulating over 6,700 citations (averaging >82 citations/paper over his whole career). His lab works at the interface between microfluidics, cancer and neurobiology. In 2001 he received a NSF Career Award and in 2014 he was elected to the American Institute for Medical and Biological Engineering (AIMBE) College of Fellows (Class of 2015). He serves on the Advisory Board of Lab on a Chip since 2006. Albert Folch is the author of four books, including "Introduction to BioMEMS", a textbook now adopted by more than 77 departments in 17 countries (including 40 universities in the U.S. alone). Since 2007, the lab runs a celebrated outreach art program called BAIT (Bringing Art Into Technology) which has produced seven exhibits, a popular resource gallery of >2,000 free images related to microfluidics and microfabrication, and a YouTube channel that plays microfluidic videos with music which accumulates ~133,000 visits since 2009.

Multi-physics couplings appearing in micro-to-macro porous media encompassing damage, transport and adsorption-induced strain (11 April, 2018)

Speaker: David Grégoire

Starting from failure analysis and crack propagation driven by mechanical or hydraulic loading conditions in quasi-brittle porous media, we will discuss some multi-physics couplings appearing in micro-to-macro porous media encompassing damage, transport and adsorption-induced strain under saturated and unsaturated conditions. Applications range from oil and gas recovery enhancement, CO2 or energy storage and nuclear containment vessel tightness assessment.

Biomaterial physical properties in tissue regeneration (11 April, 2018)

Speaker: Amaia Cipitria

Cells respond not only to biochemical but also to physical cues, such as stiffness, geometry and matrix degradability. In-vitro studies showed that hydrogel elasticity or degradation properties alone can direct cell differentiation, while scaffold geometry can control tissue growth rate. However, little is known about how these findings translate to an in-vivo scenario. Bone defect healing experiments were used to investigate how the architecture of a semi-rigid scaffold may pattern the organization of collagen fibers and subsequent mineralization in-vivo, using a 30 mm critical-sized defect in sheep tibia as a model system. The hierarchical material structure and properties of regenerated tissue were investigated using a multi-scale and multi-modal approach. Next, alginate hydrogels with varying stiffness were used for in-vivo host cell recruitment and osteogenic differentiation in a rat femoral 5 mm critical-sized defect. Current activities focus on tailoring the spatio-temporal degradation properties of novel click-crosslinked alginate hydrogels to direct cell migration and proliferation, guide spatial distribution and directionality of extracellular matrix deposition, and pattern in-vivo tissue formation.

From Superhydrophobic to Super-Slippery Surfaces (09 March, 2018)

Speaker: Professor Glen McHale

On a wet day we need coats to keep dry, windscreen wipers to see and reservoirs to collect water and keep us alive. Our cars need oil to lubricate their engines, our ships need hulls that reduce drag and our planes need wings that limit ice formation. Nature has learnt to control water in a myriad of ways. The Lotus leaf cleanses itself of dust when it rains, a beetle in the desert collects drinking water from an early morning fog and some spiders walk on water. In all of these effects the unifying scientific principle is the control of the wettability of materials, often through the use of micro- and nano-scale topography to enhance the effect of surface chemistry. In this seminar I will outline recent examples of our research on smart surface-fluid interactions, including drag reduction and flow due to surface texture,1-4 interface localized liquid dielectrophoresis to create superspreading and dewetting,5-7 lubricant infused surfaces to remove pinning,8-10 and the Leidenfrost effect using turbine-like surfaces to create new types of heat engines and microfluidics.11-12

Ultrasonic phased arrays (29 January, 2018)

Speaker: Dr Theodosia Stratoudaki

Ultrasonic phased arrays have changed the way ultrasonic imaging is perceived and are responsible for increased imaging quality, in real time. Since the '60s, they have had a profound impact in science, medicine and society, being the technology at the heart of all medical ultrasonic imaging and sonars. During the last two decades, they have seen a dramatic increase in their use for NDT, which is the focus of the presentation.

Conventional piezoelectric ultrasonic transducers are still used for the vast majority of phased array ultrasonic measurements. However, this type of transducers have certain drawbacks and limitations: a) it is a contact technique, b) the transducers require couplant, an immersion tank may be needed, c) they have a considerable size, weight and footprint which may be prohibitive when applied in places with restrictive access and  e) their delicate electrical connections and packaging may not withstand extreme environments. The question is: How could phased array technology be a part of a fast, non contact technique which would offer the same advantages in imaging quality remotely?

In this case, the new technology could address extreme environments, such as radioactive environments or extreme heat during manufacturing. It could also address places with restricted access, for example the inside of an aeroengine or the human body. Laser ultrasonics can address these issues: it is a remote, non-destructive technique that uses the light of lasers to generate and detect ultrasound. The presentation will show the challenges and future of using laser ultrasonics in order to synthesise Laser Induced Phased Arrays (LIPAs), as well as ultrasonic images of materials, using all-optical based data, for the purpose of NDT.

Trajectory optimisation of non-Keplerian, displaced Geostationary Orbits with loose position constraints (08 December, 2017)

Speaker: Yuan Liu

The geostationary orbit (GEO) is a circular, equatorial orbit whose period equals the Earth’s rotational period. It allows a satellite to be stationary above a certain point on the Earth’s equator. With the advantage of being stationary, GEO satellites are largely used for telecommunications and Earth observation. The GEO is a unique and currently very congested orbit, especially at longitudes above densely populated areas. In this presentation I will introduce some works about trajectory optimisation for the displaced GEO with loose position constraints. The works mainly focus on the hybrid-sail propellant system for both single spacecraft and multi-spacecraft formation cases.

Surface Enhanced Raman Scattering (SERS) sensors for the detection of pollutant in water (28 November, 2017)

Speaker: Dr Nathalie Lidgi-Guigui

Abstract: The Raman scattering is a well known analytical chemistry technique where the light is scattered by the vibrating bounds of a molecule. As so it gives a molecular fingerprint of a specific compound. However, Raman scattering is not a very sensitive technique. To circumvent this drawback, it is possible to take advantage of the optical properties of metallic nanoparticles (NP). When exposed to light, coherent oscillations of the free electron gas are taking place on the NP. These so called Localized Surface Plasmon (LSP) create an electromagnetic field which is the basis of the near field enhancement of Raman scattering. This electromagnetic effect is responsible for an enhancement factor that can be as high as 10^8. Another effect, the chemical effect, has a weaker contribution to the Raman scattering enhancement. Its origin is discussed among the community but is probably based on the shifting of the molecules energy levels when it is bound to the NP surface.

In this talk we will focus on the use of SERS substrate for the detection of pollutant in water. We will present results concerning hydrophobic and hydrophilic compounds. The first are organic molecules, consisting of two or more fused aromatic rings known as polycyclic aromatic hydrocarbons (PAHs). This group of compounds have received considerable attention due their toxicity and carcinogenicity. The hydrophilic compound that we have worked on is paracetamol. This is the most used drug around the world and as so it is highly found in waste water. However, in order to study its impact on the marine environment it is first needed to be able to quantify its presence.

Obviously, these two class of pollutants do not present the same issues in terms of sensing. In the first case it is important to reach a very low limit of detection when the quantification and the specificity are the key for the hydrophilic pollutants. We will present the strategy of surface functionalization we have adopted in both case that include the use of Molecular Imprinted Polymers (MIP) for the detection of paracetamol and the exploitation of pi-pi stacking for the detection of naphthalene, fluoranthene and benzo[A]pyrene.

In the last part of the talk, I will show how the nanostructured surface can play an active role in the functionalization. We have recently demonstrated that the LSP can support chemical reactions such as the well known click chemistry thiol-ene reaction. It is even possible to go further and to performed a different functionalization on different direction of a nanostructure by taking advantage of the light polarization.

Biography: After completing my undergraduate studies in material sciences at the University Pierre and Marie Curie in Paris, I followed my interest in nanotechnologies by enrolling in a doctoral program at the Unité Mixte de Physique CNRS Thales where I developed my field of expertise the nanoparticles growth and their electronic properties. After obtaining my Ph.D. in 2005, I joined the team of Prof. R. E. Palmer at the University of Birmingham where I studied the growth and deposition of size selected clusters and their interactions with proteins. The skills I developed in liquid phase AFM were valued through my second post-doc at the University of Evry. Since 2010 I am a reader at the University Paris 13. My main research interests focus on the development of highly sensitive sensors for biomolecules and pollutants. In my group, we use and develop original lithography techniques to fabricate large assembly of organized nanostructures for SERS (Surface Enhanced Raman Spectroscopy). Through the years we have developed several functionalization paths that have enable us to pre-concentrate analytes, to detect their presence in low concentration and to follow their structural evolution. Recent results are focusing on the possibility of making these sensors active by exploiting the tremendous ideas of plasmon based chemistry.

Additive Manufacturing of Metals for the Internet of Things (IoTs) (02 November, 2017)

Speaker: Prof Robert C. Roberts

The Internet of Things (IoT) is projected to create an unprecedented number of smart and connected systems, yielding a pervasive sensor and actuator network, able to interact with the real world. The diversity and complexity of these applications requires engineers to rethink their manufacturing strategies to enable rapid prototyping, lower cost, and allow customization of low-volume components that cannot be achieved using conventional mass manufacturing. Additive Manufacturing (AM), aka 3D printing, has the potential to meet this increasing demand for flexible personalized engineering, by enabling the direct manufacturing of complex components, directly from a digital design. In particular, the additive manufacturing of metals has great potential for IoT applications by enabling the fabrication of components with both useful electrical and mechanical properties. This talk highlights some developments in metal additive manufacturing technology using both inkjet-based deposition and selective laser sintering (SLS).  Inkjet additive manufacturing offers promise of low-cost microfabricated electronics, sensors and actuators on unconventional substrates by making use of organo-metallic nanoparticle based “inks” and thus requires a fundamentally different approach when compared to conventional microfabrication techniques. The process dependence on the electrical and mechanical characteristics of the resulting metal structures is explored for both Gold and Silver.  These insights are then applied to numerous applications including multilayer RF structures, microfluidic sensors, printed batteries, and strain gauges.  In contrast, Select Laser Sintering uses a laser to thermally fuse dry metal powder into solid structures. These metal structures then offer great potential not only as mechanical components, but also as sensors and actuators. Again, process parameter variation is shown to enable the modification of the electro-mechanical properties of the materials and is explored for 316L and 17-4PH Stainless Steel. SLS is then demonstrated for multiple applications including microwave horn antennas, and high-density 3D microelectrode arrays to highlight the exciting future of additive manufacturing for the Internet of Things. 

Integrated circuit and system design for next-generation multi-metabolite sensing devices (02 November, 2017)

Speaker: Dr Sara Ghoreishi-zadeh

Abstract: Next-generation implantable and wearable medical devices are emerging to address specific unmet healthcare needs, particularly those in medical monitoring and diagnostics. Monitoring of metabolites (e.g., glucose, lactate) in human body is of significant importance in health-care and personalised therapy. In this talk, I will present our sub-mW CMOS IC that enables the fabrication of miniaturised, inductively powered, and implantable devices for multi-metabolite detection. Next, I will illustrate a novel differential sensing technique to enhance the electrochemical sensing performance. I will also present promising results from our sensors that are developed, for the first time, by growing Pt nano-structures on CMOS IC. 

Despite remarkable advances in electrochemical sensor design, the constant need of the sensors for calibration remains a barrier to their diagnostic potential. I will briefly discuss our latest results showing how electrochemical impedance spectroscopy (EIS) may be used to auto-calibrate the sensors. In the second part of the talk, I will present our on-chip interface for recovering power and providing full-duplex communication over an AC-coupled 4-wire lead between active implantable devices.

Implantable and Wearable Wireless Medical Sensors (02 November, 2017)

Speaker: Prof JC Chiao

Abstract: Recent advances in micro- and nano-technologies provide unique interfacing functionalities to human tissues, with features of miniaturization and low power consumption. Interfaces between biological objects and electronics allow quantitative measurement and documentation of physiological and biochemical parameters, and even behaviors. The interfaces also provide direct modification of cells, tissues, or organs by electrical stimulation making it possible to manage chronic diseases with a closed loop between body and portable computer. Wireless communication and power transfer in the implantable systems enable in-situ sensing for freely-behaving animals or patients without constrains. Wireless networking also allows ubiquitous access to physiological information for treating complex problems in body. 

This lecture focuses on our research progress in wireless micro sensors for clinical and neurobiological applications. The systems are based on integrated platforms such as wireless energy transfer for batteryless implants, miniature and flexible electrochemical sensors, nanoparticle modified surfaces, MEMS devices, and wireless communication. Several implantable, wireless diagnosis and therapeutic systems targeting management of pain and gastric disorders will be discussed with emphases on the sensor technologies. These technologies empower new personalized medicines to improve human welfare and assist better living. Sensor device designs, fabrication, characterization, system integration and clinical experiments will be presented.

Ultrasound in Medicine and Biology (28 October, 2017)

Speaker: Chris Yang

Abstract: Medical ultrasounds are sound waves with frequencies above audible range. Clinically, 2- to 20-MHz ultrasounds are applied in imaging anatomical structure of the human body and measuring the blood velocities in arteries and veins by using the Doppler effect. By reconstructing the Doppler signal superimposing on the brightness-mode ultrasound imagine (B-mode), the venous and arterial angiography and neovascularisation can be imaged without the use of ionising radiation. The wall shear stress of the blood vessel derived from the velocity profile can be easily measured by using clinical ultrasound scanner. On the similar frequency range, surface acoustic waves are also introduced in actuating cellular particles within whole blood sample for separating target cells, such as circulating tumour cells (CTCs), which is the surrogate of cancer progression and the factor of cancer metastasis. The integration of the acoustic and microfluidic technique has shown the feasibility of manipulating CTCs for downstream characterisation by using microwave resonators.

RF & Microwave Fundamentals Seminar (28 September, 2017)

Speaker: Keysight Technologies

From the company that has been a leading innovator in Spectrum and Network measurements for 70 years, please join us for a FREE RF & Microwave Fundamentals Seminar to help improve your understanding of basic Network Analysis and Spectrum Analysis measurements, including real applications, thus improving your efficiency and effectiveness whether you are in R&D or design & test.

A vector network analyzer (VNA) is a precision measuring tool that tests the electrical performance of high frequency components, in the radio frequency (RF), microwave, and millimeter-wave frequency bands (we will use the generic term RF to apply to all of these frequencies). A VNA is a stimulus-response test system, composed of an RF source and multiple measurement receivers. It is specifically designed to measure the forward and reverse reflection and transmission responses, or S-parameters of RF components. S-parameters have both a magnitude and a phase component, and they characterize the linear performance of the DUT. While VNAs can also be used for characterizing some non-linear behaviour like amplifier gain compression or intermodulation distortion, S-parameters are the primary measurement. The network analyzer hardware is optimized for speed, yielding swept measurements that are faster than those obtained from the use of an individual source and an individual receiver like a spectrum analyzer. Through calibration, VNAs provide the highest level of accuracy for measuring RF components.

You can see our latest solutions, and expand on the practical knowledge you need to have to perform your day-to-day-measurements. Application and product experts from Keysight will be on-hand to give demonstrations and technical presentations around the latest innovations, features and capabilities that enhance the fundamental measurements.

This seminar will run through 4 main sessions:


Session 1: Network Analysis Fundamentals and Calibration
