Abstract

Water dispersable and potentially biocompatible L-cysteine-capped CdSe nanoparticles with a narrow size distribution and blue fluoresence have been synthesized by a facile method without using any additional stabilizer. FTIR study shows that CdSe nanoparticles are capped through mercapto-group of the amino acid cysteine whilst its free amino and carboxylate groups make it amenable to bio-conjugation establishing the possibility of using these as fluorescent biomarkers.
