Surface chemistry of bio/nano interfaces

The central theme of our research efforts is to measure and control single biomolecules and biologically inspired nanostructures at interfaces. We are using and developing sophisticated nanoscience tools, especially scanning probe microscopy, to greatly improve understanding and control of biomolecules on model biosensor surfaces. We are ultilizing these insights to create biosensors with substantially improved reliability, sensitivity and selectivity.
