Biosensing and molecular diagnosis have a market size of USD 29 billion (2023) and are considered an area with enormous growth and commercial potential (CAGR 8%). This multidisciplinary field requires inputs from chemists, biologists, clinicians, physicists, electronics, and mechanical engineers. Dr Ghosh closely works with several collaborators from these fields and tries to build novel assays to enable and develop biosensing devices with biomedical, agricultural, and environmental applications.
