Glucose sensor: Glucose-binding protein (GBP) covalently conjugated to a fluorescent single-walled carbon nanotube (SWNT) is shown to act as an optical switch. Hinge-bending response to glucose causes a reversible exciton quenching of the SWNT fluorescence with high selectivity (see scheme).
Keywords:carbon nanotube;fluorescence;glucose;optical modulation;periplasmic binding protein
