New Method Manipulates Particles
WEST LAFAYETTE, Ind., June 22, 2010 — Researchers at Purdue University have developed a potential new tool for medical diagnostics, for testing food and water for contamination and for crime scene forensics. The novel technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses and DNA, that are contained inside the drops. Other methods using either light or electric fields separately are able to position droplets or the particles they contain, but the new &ldqu...
