Optical sensor for in situ measurement of analytes
First Claim
1. A sensor for the detection or quantitative measurement of an analyte in fluid, said sensor being characterized in that it can function in a location beneath the surface of the skin with no physical connection to the external environment, said sensor incorporating an assay for said analyte a readout of which is a detectable or measurable optical signal, which optical signal can, when the sensor is in operation in said location, be interrogated transcutaneously by external optical means and said sensor being biodegradable or hydrolysable in vivo, biodegradable or hydrolysable material of the sensor having a pore size that permits diffusing the analyte but not assay components.

Abstract
An implantable sensor for use in the detection or quantitative measurement of an analyte in subcutaneous fluid, the sensor being biodegradable or hydrolysable in vivo. The sensor 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 means.
