Zone Plate

Image 2: This is a microscope image of the microfluidic and optical device, consisting of a flow-focus drop maker, six layers of drop splitters, followed by 64 parallel microfluidic channels, and a zone-plate array which is aligned to the microfluidic channel array at a tilt angle. ❋ Unknown (2010)

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. ❋ Unknown (2010)

In their demonstration, a 62 element zone-plate array measured a fluorescence signal from drops traveling down 62 channels of a highly parallel microfluidic device. ❋ Unknown (2010)

Unlike a typical optical detection system that uses a microscope objective lens to scan a single laser spot over a microfluidic channel, the team's zone-plate array is designed to detect light from multiple channels simultaneously. ❋ Unknown (2010)

The Harvard team's zone-plate array optical detection system, described in an article appearing in Lab on a Chip (Issue 5, 2010), may offer a solution. ❋ Unknown (2010)
