Latest Patents

Xiaohong Chen holds a patent for a "Method for depositing an enzyme on an electrically conductive substrate." This patent describes a process that results in biosensors with excellent selectivity and stability properties. The preferred biosensor includes an electrode with an enzyme deposited thereon, along with a layer of electropolymerized polymer intermingled with the enzyme. A crosslinked silane film is applied over the polymer layer, followed by a final coating of polyurethane. The preparative procedures involve electrodepositing the enzyme using an aqueous enzyme solution containing a nonionic surfactant at a concentration level exceeding the critical micelle concentration of the surfactant. In the case of a glucose sensor, the polymer layer is preferably polyphenol, while the silane film is crosslinked (3-aminopropyl) trimethoxysilane. The preferred biosensors exhibit greatly enhanced selectivity and stability.
