Group Vision
Transformation of bulk material to nano level, results in modified electrical, optical, magnetic and chemical properties. These properties can be utilized to solve problems in the area of health, energy, security and environment. Our group focuses on solving some of the above problems by new material design prepared by various( chemical/green) routes. Furthermore, we intend to develop deep insight into the problem of mass-transport of nanotherapeutics in the biological systems. We intend to formulate a mathematical model which would relate size, surface charge and mass transport rate of the nanomaterials in the biological system with tumor elasticity, porosity and mechanical properties.
Additionally, our group is also involved in developing new nanosystems capable of detecting communicable and non-communicable diseases, heavy metals and metalloids, and radioactive materials as well. Besides we are actively involved in the development of new catalyst for water splitting, hydrogen generation, CO2 sequestration, and new products.

Design and Development of Non-Linear Optical Nanomaterials

Non-linear luminescent nanomaterials based on NaYF4 host-lattice are one of the most efficient upconverters. Displaying near infrared excitatbility, narrow emission and excitation band, environment invariant emissions, and no photobleaching, best suited to application in the area of nanomedicine, imaging, biosensing, photocatalysis, energy generation, displays and opto-bi-functional devices. Despite great potential, their applicability remains limited due to restricted color availability, small extinction coefficient and low quantum yield. Our group is involved in improving quantum yield, multicolor emission, and magnetic properties of the upconverting phosphors by adding new surface functionalities. Resulting new vibrational modes,decreasing magnetic relaxations and enhanced absorption.

New Material and Devices

Ubiquitous arsenic presences in the earth crust and ground water has impending effect on global health, almost affecting 144 million population. Despite these issues, development of new optical materials that can facilitate simple, easy, reliable, sensitive and selective detection of As3+ remained limited. Our research group has been able to successfully develop new optically active 2-D materials that can detect arsenite (As3+) at 12.5 parts per trillion levels with high accuracy (99% spike recovery). We envision its use in miniaturized optical system as pocket carrying devices.
