Professor
New Jersey Institute of Technology
Sagnik is an associate professor in the Department of Chemical, Biological and Pharmaceutical Engineering in the College of Engineering. He works collaboratively with many life science researchers to stimulate novel, innovative, potentially high-risk research projects in nano/bio technology areas. His expertise includes developing chemical and biological sensors using nano/microfluidics and nanotechnology platforms; studying metal/dielectric/bio interfaces like SERS and Plasmonics; electrodynamic and electrohydrodynamic simulations from bulk to nano. He has been instrumental in developing lab-on-a-chip technology for the last five years with collaborators from biology, biochemistry, biomedical and medicine. Some of the specific projects related to biomedical applications include an electrochemical, label-free, cost-effective, carbon nanotube and shear discrimination-based diagnostic device; a nano-fluidic-based label-free, electrochemical sensor as an alternative to real-time or quick PCR (qPCR); optical nanobio sensors for FRET and SERS studies of single molecules. He is the first to show the dependence of nonlinear electrokinetic effects on the capacitive double layer and design assays based on these physical insights. Sagnik's corresponding papers are highly cited. He has been successful in the development and commercialization of technology through the licensing of multiple patents. He has guided in an advisory role many MS students and is currently supervising a Ph.D. student. Due to the interdisciplinary nature of his projects, his graduate students often work with faculty from many disciplines.
