BIOSENSORS AND BIOFUEL CELL LAB

    Dr. Pranab Goswami PhD,

    Professor Higher Academic Grade

Welcome to Biosensors & Biofuel Cell Lab

"The Biosensors and Biofuel Cell Laboratory primarily focuses on the development of advanced bioanalytical techniques and portable devices for rapid detection of analyte, mostly in healthcare and allied fields. The biorecognition agents (probes) that are intensively studied in the lab for developing such techniques include DNA (aptamers), enzymes and microorganisms. The biochemical signals that are generated as a result of the interaction between the probe and the target analytes are converted to a readable form using various transduction principles such as optical (absorbance, fluorescence) and electrochemical (amperometric, voltametric, potentiometric) signals. In this paradigm, the biofuel cell has been explored as both clean energy generating system as well as novel biosensing device. Generation and amplification of the biochemical signals encompasses exploitation of various advanced materials such as nanomaterials, nanocrystals, bio- and chemical-polymers, and biocompatible support materials. This is truly an interdisciplinary research field which involves methods and techniques from biological sciences (molecular biology, biophysics, microbiology and proteomics), nanoscience (synthesis, characterization and application of nanomaterials) and chemical and engineering sciences (analytical chemistry, electrochemistry, and microfluidics). Our lab offers opportunities for research and training in this field of cutting-edge research."
