OPTICAL SENSOR FOR IN VIVO DETECTION OF ANALYTE

摘要

A sensor for the in vivo detection of glucose comprises: components of an assay for glucose, a readout of which is a detectable optical signal which can be interrogated transcutaneously by external optical means when the sensor is implanted in vivo; and a shell of biodegradable material encapsulating the assay components whilst allowing analyte to contact the assay components, wherein the biodegradable material comprises a co-polymer having hydrophobic and hydrophilic units. A method of detecting glucose using such a sensor suitably comprises implantation of the sensor into the skin of a mammal, transdermal detection or measurement of glucose using external optical means and degradation of the biodegradable material.
