  • Publication number: 20190233869
    Abstract: A biosensor (1) is disclosed that may include at least one electrode surface (3); a reagent layer (5) disposed on top of the at least one electrode surface (3) and a reagent layer (5) formed thereon. The reagent layer (5) is formed according to the principles of the present invention, and may include a redox enzyme, a redox polymer, and a cross-linked gel. The reagent layer (5) is structured to act as a conductive matrix that traps the redox polymer and enzyme at the electrode surface.

  • Patent number: 8772443
    Abstract: The present invention is directed to polymeric materials including a copolymer of at least a first and second monomer that have desirable electrical and optical properties, such as a low band gap and near infrared (NIR) absorption, respectively. More specifically, the present invention is directed to polymeric materials with charge neutrality that display increased solubility in aqueous media while retaining their electrical and optical properties. The polymeric materials in accordance with the present invention can be modified with any desired functional group to tailor the polymer materials for a specific application. Also described are methods of making the polymeric materials in accordance with the present invention.
