Nanosensing and Technology

The Nanosensing Group conducts research directed at developing new types of sensors with nanometer dimensions (~1-100 nm) that exploit nanoscale physical, electronic, optical and/or chemical effects. We are also working to engineer the surfaces and interfaces of nanoscale sensors in order to optimize sensor performance as well as to study fundamental processes related to molecular adsorption and binding. We use a variety of measurement techniques including electrical, atomic force microscopy, laser confocal optical microscopy, and conventional optical microscopy. Currently, we have several projects that include surface plasmon resonance imaging, silicon nanowire potentiometric biosensors, advanced organic-inorganic interfaces, DNA cancer marker detection, resonant biosensors, plasmonics, surface enhanced Raman scattering, and DNA fragmentation.

	Silicon nanowires Label-free sensors detect the hybridization of an affinity complex using a variety of methods including optical, mechanical, and electrochemical techniques. We are exploring the sensing limitations of silicon nanowires (Si-NWs) to electrochemically detect probe-target binding based on surface charge modulation ... read more
