     Nanomaterials for sustainable energy and healthcare

    Understanding of the properties of nanomaterials and its application in various fields has the potential to revolutionize a wide range of scientific and technological fields. An essential aspect of the research activities of the NanoScience Research Laboratory (NSRL)  is to develop new tools and techniques for the synthesis, characterization, and study of nanomaterials and its applications in various fields for the benefits of society such as clean Energy and Healthcare.


    A clean and renewable energy generation method is the need of the hour. Fuel cell is one of the thrust areas where research is active to solve the issue of energy crisis. Another important energy source is hydrogen, and hydrogen production through water splitting is an active and hot research field. Similarly the storage of energy demands more development in the area. Energy storage systems such as batteries and supercapacitors are highly demanding.


    At NSRL we work on the application of nanomaterials in



    Development of electrochemical biosensors with enhanced performance has gained increasing importance owing to their wide range of applications in various fields ranging from medical diagnostics and health care,  environmental monitoring, industrial manufacturing to defense and security.


    At NSRL we work on the application of nanomaterials in
