摘要： A glucose sensor for measurement of glucose in subcutaneous tissue, the sensor comprising: a probe for subcutaneous insertion, the probe containing an indicator system comprising a receptor for selectively binding to glucose and a fluorophore associated with said receptor, wherein the fluorophore has a fluorescence lifetime of less than 100ns; a detector head which is optically connected to the probe and which is for location outside the body; a light source; and a detector arranged to receive fluorescent light emitted from the indicator system, wherein the light source and detector are optionally located within the detector head; wherein the sensor is arranged to measure glucose concentration in subcutaneous tissue by monitoring the fluorescence lifetime of the fluorophore.
