A polyaniline with near-infrared optical response to saccharides

Communication: A sugar-binding polymer film capable of continuous sensing a rises from the copolymerization of aniline and 3-aminophenylboronic acid. I ts absorption spectrum between 500 and 800 nm undergoes large changes on ad dition of various saccharides at neutral pH, changes which are dependent on the saccharide concentration and are fully reversible. These films represe nt an interesting alternative to enzyme-based glucose sensors because of th eir ease of preparation, compatibility with LED and diode laser light sourc es, and their thermal and temporal stability.
