Filed:

Sep 8, 1998

Appl. No.:

9/149506

Inventors:

Wenbin Jiang - Phoenix AZ
Barbara M. Foley - Phoenix AZ
Sean Gallagher - Scottsdale AZ
Davis H. Hartman - Chandler AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

C12Q 168

US Classification:

435 6

Abstract:

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.

Abstract:

A bio-molecule analyzer including a plurality of test sites on a transparent substrate, each test site having probe molecules attached thereto. An array of addressable light sources are positioned in optical alignment with a corresponding test site. A solution containing sample molecules is positioned in contact with the plurality of test sites. A detector array having a plurality of photodetectors positioned in optical alignment with the array of addressable light sources, one photodetector corresponding to each light source, and a light filter positioned between the detector array and the plurality of test sites for absorbing the light from the light sources and transmitting the light from the test sites to the detector array.
