Live demonstration: An extended-gate CMOS sensor array with enzyme-immobilized microbeads for redox-potential glucose detection

摘要

Glucose detection associated with CMOS-based electronics has great potential from the viewpoints of cost, form factor, and simplicity. There are two conventional approaches for emerging CMOS-based glucose detection. One is based on direct charge detection, and another is based on pH detection. Unfortunately, these methods are susceptible to buffer conditions such as the salt concentration and pH buffer capacity, which can seriously degrade their accuracy and reliability.
