Research in our group is focussed on the synthesis of functionalized nanostructured materials and their nanocomposites through indigenously developed, novel and simple solution phase processing techniques i.e., through “bottom-up” approach.
Nanostructured materials, by virtue of their boundary surface-determined properties, bring about novel properties (e.g., extraordinary mechanical, electric, magnetic etc.) compared to their bulk counterparts. The challenge is to use chemistry to manipulate the particulate dimensions/ morphologies of a material to accomplish the desired nanostructure or to modify / functionalize their surface through appropriate manoeuvring of the chemical composition and the processing parameters. The motivation is to study the structure/property correlations of the nanostructures for exploiting their technological benefits in the field of – catalysis, sensors, pigments, ferroelectric/ magnetic device fabrication, separation technology, biomedical applications etc. The systems of interest include: Magnetic oxides (spinel ferrites, orthoferrites, iron garnets); Structural and other mixed oxide materials (e.g., chromites, aluminates, zirconates, vanadates, molybdates, tungstates); Double & complex ferroelectric oxides with perovskite/ layered type perovskite / tetragonal tungsten bronze structures; Curved nanostructures of layered MoS2 and WS2 etc.
Our recent research-ventures, carried out in collaboration with the School of Medical Science and Technology, IIT Kharagpur has been on the development of biocompatible nanostructures/ nanocomposites for (a) fabrication of nanocarriers for targeted drug delivery for the treatment of cancer (both, in-vivo and in vitro studies) using surface functionalized magnetic nanoparticles, fluorescent carbon dots, hollow / mesoporous inorganic nanostructures; (b) spectroscopic detection of toxins (such as, hydrogen peroxide and heavy metals) using carbon-based nanocomposites; and (c) development of florescent probes for biomedical applications.
