 Research Overview

Interface control is one of the key challenges for harnessing the tunable opto-electronic properties of nanoparticles, which have attracted much interest in modern research due to their potential applications in the fields of biotechnology and materials science. The focus of my research activity is on the development of novel strategy for nanomaterials synthesis, and controlling their opto-electronic properties in the nanoscale using organic stabilizer. The materials of interest are noble metal nanoparticles (gold and silver), transition metal hydroxide/oxides nanoparticles and carbon-based nanoparticles. Because of chemistry background and have expertise in working with multidisciplinary projects till date concerning nanomaterials, I give emphasis my research on nano- and/or materials-chemistry involving organic-inorganic hybrid materials. The aspect of my research is on nanoscience and materials chemistry comprising both synthesis methodologies and their suitable applications in nanomedicine, sensor/detection, catalysis, energy/data storage etc.
