Latest Patents

Fisher's latest patents focus on an innovative optical assay technique. This technique involves coating a predetermined part of a pre-formed surface on a substrate with a thin film of a material capable of binding the species to be assayed. The pre-formed surface is optically active with respect to radiation over a specific band of wavelengths. The process includes contacting the coated surface with a sample and observing the optical properties of the pre-formed surface to determine any qualitative and quantitative changes resulting from the binding of the species. The optical properties can be monitored before and after the sample contact, or during the process itself. The pre-formed surface is preferably a grating, and an article for use in this technique comprises a substrate carrying the pre-formed surface, which is coated with the receptive material for the species to be assayed.
