2003 MAR 26 - (NewsRx.com & NewsRx.net) -- University of Chicago physicists can use multiple beams of light to selectively sort microscopic particles, biological cells, and large molecules, they reported at the American Physical Society meeting in Austin, Texas.
Manipulating these beams of light has led to one of the newest techniques in microfluidics, the science of transporting fluids through networks of miniature channels. University of Chicago physics professor David Grier calls the new technique "optical fractionation," because it involves using light to sort one fraction of objects from another.
"It's a new approach based on very old principles," ...
