Paper Abstract

Polymer microarrays were used as a high-throughput tool to discover optimal polymer matrices with abilities to entrap sensor molecules while displaying good pH sensitivity. The identified lead polymer poly(methyl methacrylate-co-2- (dimethylamino) ethyl acrylate) (PA101) was dip coated, onto the end of an optical-fibre to fabricate a robust, rapidly responding and robust optical fibre pH sensor, which was used to measure subtle pH changes in lung tissue validating its capabilities for biomedical applications.
