Molecular electronics and bioelectronics require control over electronic communication between electrodes and molecules. Waldeck’s group investigates the electron exchange between biomolecules and electrodes over distances of 1- 4 nm. We have quantified electron tunneling through nm thick films and single molecules on metal surfaces. We are selectively binding protein molecules to electrodes, and optimizing the electrical communication, through manipulation of the electron tunneling pathways and the local solvation of the protein. In addition, we are collaborating with a number of other groups on the development of novel nanoscale sensors based on plasmonic gratings, nanocrystal materials, and conjugated polyelectrolytes.
