ELECTRICAL BIOSENSOR FOR DETECTING A SUBSTANCE IN A BODILY FLUID, AND METHOD AND SYSTEM FOR SAME

摘要

An electrical biosensor for use with a reader is provided and can include an electrical component configured such that the coupling of a targeted substance to a surface of the electrical component changes an electrical characteristic of the electrical component. A protein immobilization structure can be disposed on the surface and can include an array of functionalized structures for interacting with a substance in a sample of a bodily fluid. Each functionalized structure can include a protein capable of binding to a targeted chemical substance or substance in the sample whereby an electrical reading can be obtained by a reader to determine the concentration level of the targeted substance in the sample.
