Nanotechnology is to understand and control matters at dimensions smaller than 100 nanometers. At this dimension, the physical, chemical, and biological properties of materials differ significantly from the properties of bulk matter, where unique phenomena enable novel applications. Research in nanotechnology involves fabricating/synthesizing, characterizing, modeling, and manipulating matter at this nanometer scale. Nanotechnology is a rich, dynamic, and expanding research area in the Department of Physics and Astronomy. Current research activities include nanomaterial fabrication/synthesis, nano-optics, nano-magnet, spintronic, chemical and biology sensing, renewable energy applications, medical imaging, disease treatment and drug delivery.
