BIO-MOLECULE ANALYZER WITH PHOTOSENSITIVE MATERIAL AND FABRICATION

摘要

A bio-molecule analyzer (10) includes an array (35) of addressable light sources, a photoconductive layer (16) of material having a layer (14) of electrically conductive material on a surface thereof mounted on the array of addressable light sources, and a plurality of test sites (30) on an opposing surface (24) of the photoconductive layer of material defined by the plurality of light sources. A solution (22) containing a plurality of bio-molecules is positioned in electrical contact with the plurality of test sites. An electrical potential is connected (18, 20) between the solution and the layer of electrically conductive material, whereby the array of addressable light sources emit beams (33) of light through a plurality of portions (34) of the photoconductive layer of material to define the test sites and complete electrical circuits between the layer of electrically conductive material and the solution.
