Title:
AQUEOUS CONDUCTIVE DISPERSION BODY, PRODUCTION METHOD FOR AQUEOUS CONDUCTIVE DISPERSION BODY, BIOSENSOR AND PRODUCTION METHOD FOR BIOSENSOR
Document Type and Number:
Japanese Patent JP2019084519
Kind Code:
A
Abstract:
To provide an aqueous conductive dispersion body capable of more efficiently producing a biocompatible electrode, to provide the electrode restraining non-specific adsorption to measure the concentration of a measuring object (for example, a glucose) at high sensitivity and stably for a long term, and to provide a biosensor using the electrode.SOLUTION: There is provided an aqueous conductive dispersion body including a conductive material (A), betaine polymer particles (B), a dispersant (C) and an aqueous liquid medium (D). The betaine polymer (B) includes as essential components, the betaine monomers (b1) to (b3) having at least any structure represented by general formulas 4 to 6, and the polymer particles having an average particle diameter of 50 nm or more are dispersed in the aqueous liquid medium (D). The dispersant (C) dissolves in the aqueous liquid medium (D), or the particles having the average particle size of less than 50 nm are dispersed in the medium (D).SELECTED DRAWING: Figure 1
