An extended-gate type organic field effect transistor functionalised by phenylboronic acid for saccharide detection in water

Saccharides in water are detected electrically using an extended-gate type organic field effect transistor (OFET) functionalised by a phenylboronic acid monolayer. The response patterns of the mono-saccharides are significantly different, suggesting that OFET devices can successfully read out the saccharide recognition behaviour of boronic acids and be potentially applied to healthcare devices modified with supramolecular receptors.
