Application

Polymeric membrane material for chemosensors and biosensors

Polyurethane was used as an outer coating membrane to increase stability and the linear range of the sensor during development of glutamate microbiosensor. It may also be suitable in investigating the thermal degradation of α,γ-diphenyl alkyl allophanates and carbanilates for crosslinking sites using pyrolysis-high-resolution gas chromatography/FT-IR (Py-HRGC/FT-IR).
