New Fluidic Microchip Uses Lasers and Electric Fields to Separate Particles and Microbes by Size

Researchers at Purdue University in Indiana have engineered a microfluidic chip that uses a laser and electric fields to produce "whirlpools" for separating particles and microbes by size. This rapid electrokinetic patterning is "a powerful tool for development of a high-performance on-chip bioassay system," according to Steven T. Wereley, a professor of mechanical engineering at Purdue.

The technology enables the researchers to position specific types of particles for detection and analysis.
