Optical Detection of Suspended Micro-Objects Using Array Waveguides

Detailed Technology Description

Researchers at UC San Diego have introduced micro fabricated electrodes into fluidic channels to facilitate optical detection by controlling and manipulating the positions, angles, and populations of analytes in micro-fluidic channels, such as cells and DNA, via a dielectrophoretic effect. The researchers have fabricated, using novel technology, microfluidic-photonic-dielectrophoretic integrated circuits with channel waveguides. This represents a new class of circuits particularly attractive to lab-on-a-chip and biomedical applications. [Aspects of this research have been published; see The 17th Annual Meeting IEEE/LEOS, Technical Digest]
