Dr. Gorachand Dutta is Assistant Professor at School of Medical Science and Technology, IIT Kharagpur. He received M.Sc. degree in Chemistry from Indian Institute of Technology, Guwahati, India. His research interests include the design and characterization of portable biosensors, biodevices, and sensor interfaces for miniaturized systems and biomedical applications for point-of-care testing. He received his Ph.D. in Biosensor and Electrochemistry from Pusan National University, South Korea, where he developed different class of electrochemical sensors and studied the electrochemical properties of gold, platinum, and palladium-based metal electrodes. He completed his postdoctoral fellowships in the Department of Mechanical Engineering, Michigan State University, USA, Department of Chemistry, Pusan National University, South Korea, and Centre for Biosensors, Bioelectronics and Biodevices at University of Bath, UK. During his research tenure in USA and South Korea, Dr. Dutta inventedan enzyme-free, disposable miniaturized immunosensor chip using micropatterned electrode and wash-free method for the development of mobile phone-based platforms for fast and simple point-of-care testing of infectious and metabolic disease biomarkers. He has expertise on label-free multichannel electrochemical biosensors, electronically addressable biosensor arrays, aptamer- and DNA-based sensors, and surface bio-functionalization. Dr. Arindam Biswas received M. Tech. degree in Radio Physics and Electronics from University of Calcutta, India, in 2010 and Ph.D. from NIT Durgapur in 2013.
