Welcome to the Willets Lab at Temple University
The Willets lab is interested in understanding how heterogeneity at nanoscale interfaces 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 interfacial heterogeneity affects a range of applications including sensing, energy harvesting and transfer, and surface reactivity.
