Novel optical solid-state glucose sensor using immobilized glucose oxidase
Meso-tetra(4-carboxyphenyl)porphine (CTPP4) binds reversibly to immobilized glucose oxidase (GOD), resulting in an absorbance peak for the CTPP4-GOD complex at 427 nm. The absorbance intensity of the 427 nm peak is reduced upon exposure to glucose, which causes the dissociation of CTPP4 from GOD. The change in absorbance at 427 nm shows linear dependence on glucose concentration from 20 to 200 mg/dL (1.1-11.1 mM). (C) 2002 Elsevier Science (USA). All rights reserved.
