Biosensors Research


The accurate and on-time diagnosis of diseases is essential for its early treatment. Most of the currently used diagnostic techniques are laboratory bound, involve complex procedures, require sophisticated instruments, and expert personal to operate them. Thus, it is imperative to develop a sensitive, selective, affordable, robust, and portable biosensors for point-of-care diagnostics tools.Biosensors are electronic devices in which biomolecules such as enzymes, antibodies, nucleic acids, whole cells, etc. are used as a sensing element.

The development of a simple, reliable, and low-cost sensors for the analysis of environmental contaminants is also equally important owing to the severe health hazards caused by environmental pollutants. Our research group focuses on the development of reliable, low-cost sensing tools for the detection of food, water, and hospital-borne pathogens, detection of clinical biomarkers, and environmental pollutants such as antibiotics, pesticides, and heavy metal ions. We also work on the synthesis of functional nanomaterials tofabricate asensitive and selective biosensor for a wide range of applications.
