Nanoparticles show new and interesting properties different from bulk materials due to their extremely small size (diameter), large specific surface area and spatial anisotropy. It is thus critical to understand the variables that control its synthesis, leading to a desired application. Control of mean nanoparticle size, particle size distribution and specially, anisotropic particle shapes is the first step in many of these applications, involving enhanced adsorption and reaction rates.

We have already developed a working prototype for killing and removal of
E. coli from water. It is based on our synthesized nanocomposite, made
of Ag-Cu nanoparticle impregnated on granular activated carbon and
packed into a filter column, which is driven by gravity-head of the water

We have already developed in our lab. an autonomous device for
real-time, water quality monitoring by both physical and chemical
sensors (some of the sensors being developed by us), with years of
earllier work in our lab. by a multidisciplinary team of Chemical, Mechanical and Electrical Engg. students.
