A researcher from the Department of Chemistry, University of North Bengal, West Bengal, is using chemical reactions to modify the surface of nanoscale crystals called quantum dots (QDs) for fabricating optical materials that can have sustainable applications in optical sensors, light-emitting usages, composites and fluorescent biological labels.
What are Quantum dots?
- Quantum dots (QDs) are man-made nanoscale crystals that that can transport electrons. When ultraviolet light hits these semiconducting nanoparticles, they can emit light of various colors.
- These artificial semiconductor nanoparticles have found applications in composites, solar cells and fluorescent biological labels.
- Quantum dots enable researchers to study cell processes at the level of a single molecule and may significantly improve the diagnosis and treatment of diseases such as cancers.
