Project title:  A lab-on-chip system to continuously monitor wound chronicity through an enzymatic electrochemical sensing platform


Project Supervisor: Dr. Shekhar Bhansali

Research Interest

My research interests lie in the design and micro-fabrication of point of care biosensors, for in-vitro transdermal investigation of bio-analytes using electrochemical sensing. Through my studies, I explore the growth, chemistry and bio-chemistry of different materials at the micro/nano-scale, study their properties and behavioral changes under different environmental conditions. Progressing towards advancement in health diagnostics, I have a keen interest in the design and fabrication of miniaturized, lab-on-chip devices which can employ ultra low power (µW range) for continuous, point-of-care monitoring of bio-analytes in the human body. Design of a biosensor for the concerned purpose involves using the right kind of material which is bio-compatible and entails non-invasive, label free sensing techniques for continuous, repeatable, reusable, convenient and hassle-free monitoring of bioanalytes.
