Marriage of microfluidics and optics could advance lab-on-a-chip devices
Date:2/16/2010

l approacheffectively like 62 microscopeswe can get very high measurement or data rates," says Crozier. "This device has shown we can measure up to 200,000 drops per second, but I think we can push it even further."

Nanophotonics experts Schonbrun and Crozier originally developed the zone-plate technology to enhance optical tweezers so they could grab particles in a liquid using light. Using the high numerical aperture that makes efficient optical tweezers, they realized that arrays of zone plates could also be used to implement an efficient and scalable optical detection platform.

The researchers, who have filed a patent on their invention, are optimistic that with further research and development, the device could enhance a range of microfluidic and microfluidic-based lab-on-chip devices and speed the advance of using them for applications such as in-the-field biological assays.
