Microscope Tracks Nanoparticles in 3-D

Microscope Tracks Nanoparticles in 3-D - Video of a fluorescent polystyrene sphere 190nm in diameter captured with the NIST orthogonal tracking microscope. The view is of an upper-left corner of the sample well. The glowing ball at the bottom right of the image is the particle, the other two moving glows are reflections.

A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions.
