Paper Abstract

FTIR-ATR-spectroscopy can be used to design an optical glucose sensing system. The building of an immobilized enzyme layer, via 3-Aminopropyltriethoxysilane (3-APTS) and glutaraldehyde leads to a stable glucose oxidase (GOD) film on a germanium crystal with a thickness smeller than the penetration depth of the IR-radiation (<0.5 um). The system measures the absorbance of the 1153 cm gluconic acid band and exhibits a good linearity (for glucose concentrations of 0.52 - 20 mM) with a correlation coefficient of 0.96.
