Heavy metal-free Quantum Dots Synthesis / Surface Chemistry / Size and Shape Control
Optical engineering of quantum dot nanocrystals has the potential to generate nanostructured materials that can revolutionize the research fields of chemistry, biology and physics. A major challenge is the preservation of the luminescence property of the quantum dots and the generation of high fluorescence quantum yield after conversion of the hydrophobic nanocrystals to hydrophilic nanocrystals. Secondly, the inherent toxicity of quantum dots has hampered their utilization in real-life applications. My group’s research is focused on the development of novel synthetic fabrication methods for single ensemble luminescent nontoxic quantum dots via band gap optical engineering to produce quantum dots with unique optical properties, well-defined quantum size and shape morphology and excellent photostability.
Engineered band gap alloying of quantum dots
My group’s research is focused on the band gap engineering of semiconductor quantum dot nanocrystals. This involves developing optimized synthetic parameters, discovery of new ligands and unravelling the right blends of precursors to engineer the quantum dots shape and size with the primary aim of tuning the QDs size across the UV/vis to the near infrared region.
Quantum Dot Hybrid Nanostructures
My group’s research is focused on the development of quantum dots hybrid nanostructures that combines the properties of both the quantum dots and other nanomaterials to create assembled nanostructured systems with unprecedented properties.
Nanobiosensors
My group’s research is focused on the development of point-of-use colorimetric, fluorescence, electrochemical and surface-enhanced Raman scattering nano-based biosensors for food, defense & security, biomedical and environmental applications.
