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.

1-14. (canceled)
A method for making a sensor for detecting the presence or measuring the concentration of a target analyte, the method comprising:
- (i) polymerising a first prepolymer composition comprising 1 mol % or less of a crosslinking agent by mol of the first prepolymer composition to form a first phase comprising a first crosslinked polymer;
- (ii) introducing a second prepolymer composition into the first phase;
- and
- (iii) polymerising the second prepolymer composition to form a second phase comprising a second crosslinked polymer such that an optical grating is formed by the first and second phases;
- wherein one of the first and second crosslinked polymers comprises a target analyte recognition agent.
