Title:
HIGH MOLECULAR WEIGHT REDOX POLYMER AND BIOSENSOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/064774
Kind Code:
A1
Abstract:
The present disclosure provides a means for inhibiting or suppressing the outflow of a redox mediator constituting a reagent layer in a probe of an implantable biosensor, especially a means capable of improving storage stability (durability) while maintaining glucose measurement sensitivity. The high molecular weight redox polymer according to the present disclosure is represented by general formula (A) [in the formula, X- represents an anion species, L represents a linker, Poly represents a high molecular weight polymer, and R1-R8 each independently represent a hydrogen atom or a substituent.]. The biosensor according to the present disclosure has a working electrode, a counter electrode, a reagent layer disposed on the working electrode, and a protective film covering at least the reagent layer, and the reagent layer includes an oxidoreductase that oxidizes or dehydrogenates the analyte and at least one high molecular weight redox polymer represented by general formula (A).
