Optical manipulation of light-absorbing particles takes to the air
Ashley G. Smart
The idea that light can move matter is not new—Johannes Keplersuspected as much some 400 years ago when he noticed that the tails of comets always point away from the Sun. That suspicion was formalized in 1871 with James Clerk Maxwell's prediction of radiation pressure—the force imparted on a body by refracted, reflected, or absorbed light—and confirmed in 1900, when Pyotr Lebedev observed the effect in experiments.

Commercial optical traps emerge from biophysics labs
Jermey N. A. Matthews
What if determining your blood type took a few seconds and a few dozen red blood cells instead of several minutes and milliliters of blood? To that end, one company is building on a two-decades-old invention that harnesses laser radiation to noninvasively trap and manipulate submicroscopic particles.
