Bio-molecule analyzer with photosensitive material and fabrication

摘要

A bio-molecule analyzer includes an array of addressable light sources, a photoconductive layer of material having a layer of electrically conductive material on a surface thereof mounted on the array of addressable light sources, and a plurality of test sites on an opposing surface of the photoconductive layer of material defined by the plurality of light sources. A solution containing a plurality of bio-molecules is positioned in electrical contact with the plurality of test sites. An electrical potential is connected between the solution and the layer of electrically conductive material, whereby the array of addressable light sources emit beams of light through a plurality of portions 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.
