Patent ID: 11859231
Assignee: MEDTRONIC MINIMED, INC.
Field: Measurement (Instruments)
Classification: CPC C  A  G | IPC A  C  G

Claim 0:
1. An electrochemical analyte sensor comprising:
a base layer;
a working electrode disposed on the base layer; and
a multilayer analyte sensor stack disposed upon the working electrode comprising:
(a) an analyte sensing layer disposed directly on the working electrode, wherein the analyte sensing layer detectably alters the electrical current at the working electrode in the presence of an analyte;
(b) a high-density amine layer disposed over the analyte sensing layer, wherein the high-density amine layer comprises polymers having repeating amine groups; and
(c) an analyte modulating layer disposed over the high-density amine layer, wherein the analyte modulating layer modulates the diffusion of analyte from an external environment to the working electrode; wherein:

the high-density amine layer comprises a first side in direct contact with the analyte sensing layer or the analyte modulating layer.
