Abstract

We demonstrate a novel field-effect saccharide sensor device using an AlGaN/GaN heterostructure functionalized with a chemical receptor, featuring a thiol group, alkane chain linker and a simple boronic acid. Fabricated devices were demonstrated to electronically detect buffered saccharide solutions (fructose, galactose and glucose) of varying concentrations. These results provide proof-of-concept for the development AlGaN/GaN-based sensor devices incorporating boronic acid receptor chemistry.
