An implantable sensor for use in the detection or quantitative measurement of an analyte in subcutaneous fluid, and that is biodegradable or hydrolysable in vivo, incorporates an assay for the analyte, the readout of which is a detectable or measurable optical signal which can, when the sensor is in operation in a subcutaneous location, be interrogated transcutaneously by external optical apparatus. |
