Optical Binding Movie

We have been working on an experiment to demonstrate evanescent wave optical binding of microparticles.

The latest movie from this experiment is here and on our YouTube channel. In this movie you can see 1 micron diameter silica microparticles suspended in water above the surface of a glass prism.  The microparticles organise into 1D chains when exposed to the evanescent field of a laser beam reflected from the surface below.
