CEE Distinguished Professor Ming Wang was awarded a patent for “Durable enzyme-based biosensor and process for drop deposition immobilization.”
Abstract Source: USPTO
A sensor having improved shelf life is provided for determining concentration of a biomarker in a liquid sample. The sensor functions by electrochemical detection and requires use of a biomolecule, e.g., an enzyme that catalyzes an electron transfer reaction specific for the biomarker. The sensor requires use of a quaternary ammonium compound as a bio-linker. It further requires crosslinking of the biomolecule for improved stability.
