Nanomaterials are cornerstones of nanoscience and technology and have created a high interest in recent years by virtue of their unusual and unique properties and the various potential applications. It has found wide range of applicability in various fields such as sensors, opto-electronic devices, energy storage, bio imaging, and water treatment to name a few. Sensors based on nanomaterials, rely on the highly active surface and the high specific surface area to initiate a response even with a minute change of concentrations of the analyte species, thus enabling highly efficient sensors. Electrochemical (EC) sensor based on nanomaterials are proved to be highly efficient. Certain nanomaterials like Graphene, transition metal chalcogenides, Mxenes etc have proven to be highly applicable because of their additional property such as improved conductivity and stability. Our group focuses on selecting nanomaterials based on the interactions between the electrode materials and the analytes of choice and applying the materials for EC sensing. Our group focus is to devise or adapt synthetic strategies which are simple, cost effective and benign to the environment. We have done works based on nanomaterials such as 2D layered materials, graphene, graphene quantum dots and metal nanoclusters. Figure 1 gives the schemes of some of the EC sensing research done by our group
