Overview

Our research activities are in the areas of transport phenomena, reaction engineering, materials processing and micro/nano fabrication leading to the technology development of chemical sensors - utilizing both printable flexible electronics based platforms as well as conventional silicon electronics based platforms. We study the physical modification and chemical modification to fabricate functional sensing surfaces, transport phenomena of the analytes to these surfaces (including in microfluidic units), the specific recognition reactions at these surfaces, charge transport in the semiconducting materials, and device design (including transistors and arrays). There is an effort towards understanding the sensing mechanisms. These chemical sensors (including biosensors) have applications in healthcare, environmental monitoring, industrial safety, and security.
