Glucose responsive polymer brushes were synthesized on gold substrates and microcantilever arrays. The response properties of these brushes were evaluated by exposing them to different glucose concentrations for a range of pH values. This work demonstrates the potential for polymer brush-functionalized micromechanical cantilevers as glucose detectors. Furthermore, the work demonstrates that stimulus-responsive polymer brushes on micromechanical cantilevers have a significantly larger bending response due to glucose binding compared with self-assembled monolayers.
