(Phys.org)—NIST Center for Nanoscale Science and Technology researchers Gregg Gallatin and Andrew Berglund (now at Quantifind in Palo Alto, CA) have determined the optimum path in which to scan a laser beam in order to track a fluorescing nanoparticle as the particle moves inside a fluid or gas in two or three dimensions.
