DNA-based nanofabrication Plasmon-based optical antennas
Dielectric optical antennas Biochemical sensors

We are interested in the large-scale fabrication of optical antennas to enhance light-matter interactions at the nanoscale. In particular, we develop DNA templated fabrication techniques to produce nanoparticle groupings with controlled chemical environments. We preferentially use gold particles but have experience with silver colloids and semiconductor quantum dots. Optical antennas are used for applications ranging from quantum optics (to optimize single photon sources) to sensing (using plasmon rulers).
