"Imagine if you could reach out with your hands and grab a microscopic object – and watch as you move it about with micron precision or even spin it round. You could, for example, assemble a machine out of tiny components or poke and probe a bacterium or two.

Well, now all you need is an iPad – and a connection to a holographic optical tweezers system – thanks to a new software application created by researchers at the University of Glasgow and University of Bristol.

Holographic optical tweezers use a spatial light modulator to split and steer a laser beam so that it can be used to manipulate multiple microscopic objects in 3D."
