Our research group is focused on developing novel functional nanoscale devices and their application as sensors to measure a variety of different measurands. Using modern fabrication and synthesis techniques we have the ability to engineer materials with near atomic scale precision, which has facilitated advancements in many application areas. Currently, our research efforts are aimed at developing nanosensors for medical diagnostics that employ nanoscale physical and chemical effects to enhance the sensitivity of detecting ultra-low concentrations of target molecules in small sample volumes.
