The Willets lab is interested in understanding how heterogeneity at the nanoscale impacts the function and properties of materials. Much of our research focuses on noble metal nanoparticles, typically gold and silver, which are both optically-active through the excitation of localized surface plasmons as well as electrochemically-active, which enables them to behave as nanoscale electrodes. We use a variety of techniques including fluorescence, Raman, single molecule imaging, super-resolution imaging, electron microscopy, atomic force microscopy, and electrochemistry to understand how nanoscale heterogeneity affects materials behavior.
