Research

For most of the advanced applications, there is a dominant requirement that nanoparticles in fact

have organized assemblies with well defined spatial separation, both in solution and solid state. Such

self-assembly usually consists of intricate building units that are used to create well defined

structures with multi-dimensional ordering. The resulting self-organized structures give rise to inter-

nanoparticle interactions ranging from dipole-dipole interactions to exchange interactions such as

delocalization of carriers. These are then the cause of the overall novel properties exhibited by the

organized supra-particle assembly. Current research activities are focused on the various

perspectives of such functional supramolecular structures (mainly semiconductors, perovskite

materials, photocatalyst, chalcogenides, biomolecules, layered materials, noble metal etc.).

Specifically it involve:

Materials Chemistry- Development of novel versatile synthetic approaches based on soft chemistry

to fabricate a variety of functional materials possessing mainly metal oxide frameworks, perovskites,

chalcogenides, and noble metals (Au, Ag and Pt etc.) for various applications such as opto-electronic,

biosensor and photocatalysis etc. Exploration of fundamental insight into the science of structure-

property relationship of hierarchical nanostructures.

Engineered Nanostructured Materials for Solar Hydrogen Generation- Exploration and

engineering corrosion-resistant photocatalyst-semiconductors that exhibit the optimal conduction and

valence band edge alignment for PEC applications. An understanding of surface chemistry /

electrochemistry / band gap engineering involved in photo-catalysis. Design of bio-

photoelectrochemical systems to mimic the natural photosynthesis for energy generation.

Host-Guest Chemistry- Encapsulation studies of bio-/organic- molecules which are susceptible to

their spatial confinement and their interactions with the surrounding species. Fabrication of stimuli

responsive biodegradable polymer nanostructures for targeted drug delivery applications.

Nanostructured Hydroxyapatite-titania Bio-implant Scaffolds- Development porous

nanostructured HAp scaffolds with improved mechanical strength, corrosion resistance and cellular

biocompatibility.
