Abstract
The application relates to a device and method for performing analyte detection, especially biomolecule detection. The device and method combine photo-induced charge separation in label materials and field effect transistors as sensors, resulting in more sensitive, specific and/or selective detections of biomolecules in multiplex assays, such as immunoassays and DNA microarray assays. The embodiments of the invention also encompass a device and method that comprise an array of electrical sensors, such as field effect transistors, and binding complexes for simultaneous multiplex detection of analytes.
