Research Overview

Our research focuses on the development of various nanomaterials for various applications in particular drug delivery, bioimaging, solar H2 generation, catalytic reactions, and solid state lightings. We also investigate growth and stabilization mechanism which will useful to design the material with multifunctional properties. Our ultimate goals are:

1. To make targeted multifunctional nanomaterials for optical/magnetic resonance imaging (MRI) agents as well as drug delivery vehicles.
2. To make lanthanide based nanodevices by using its opto-magnetical properties
3. To select and design new nanomaterials for solar H2 generation.
4. To make new novel catalysts
