His contributions focus on advancements in enzyme electrodes and heat-sensitive recording materials, showcasing his dedication to improving scientific applications.

Latest Patents

Yuasa's most recent patents include the "Preparation of a selectively permeable membrane for an enzyme electrode" and "Heat-sensitive recording materials." The selectively permeable membrane is designed to facilitate the passage of substances produced by enzyme reactions while simultaneously blocking higher molecular weight materials. This intricate process involves creating a mixture of resin emulsion and water-soluble polymer, which is then subjected to ionizing or ultraviolet irradiation. An immobilized enzyme membrane is affixed to this membrane, resulting in a sophisticated enzyme electrode structure.

The heat-sensitive recording material consists of a support coated with a specialized recording layer. This layer contains a color former and a color developer that react upon contact, producing a visible color. An interlayer of water-soluble resin or water-dispersible resin is created over the recording layer, followed by an overcoat layer equipped with macromonomers and resins that can be cured via electron beams. This innovation allows for improved performance and versatility in recording applications.
