Abstract
The present invention relates to sensors for detecting the presence or measuring the concentration of a target analyte, the sensor comprising: (i) a first phase comprising a first crosslinked polymer; (ii) a second phase comprising a second crosslinked polymer; and (ill) a target analyte recognition agent; the first phase and second phase arranged to form an optical grating. The first crosslinked polymer comprises low amounts of a crosslinking agent. The present invention also relates to methods of making a sensor for detecting the presence or measuring the concentration of a target analyte.
