This patent details a glucose sensor comprising a conducting back electrode, a silicon substrate, a dielectric layer, a pH sensing layer, and a chemical layer in contact with an aqueous solution. The sensor also includes a conductive electrode disposed on the dielectric layer, facilitating glucose detection.

This patent presents methods for preparing a patterned directed self-assembly layer by providing a substrate with a block copolymer layer. The process involves exposing the block polymer layer to gas pulsing carbon monoxide, configured to selectively remove specific patterns of phase-separated polymers, aiding in semiconductor fabrication.

This patent describes a biosensor comprising a sensing element formed on a buried oxide layer of a substrate, providing communication between source and drain regions. It includes a gate dielectric layer defining a sensing surface, a passive surface surrounding the sensing surface, and a compound bound to the sensing surface, specifically configured to bind target molecules for detection.

This patent provides a mechanism for determining the isoelectric point of a molecule by measuring capacitance versus voltage curves of a capacitor with and without the molecule bound to a functionalized material on the dielectric layer, facilitating biomolecular analysis.
