Synthesis of smart graphene quantum dots: A benign biomaterial for prominent intracellular imaging and improvement of drug efficacy

The present study portrays the synthesis, characterization and different biological applications of hetero atoms (N and S) doped smart graphene quantum dots (NS-GQD). NS-GQD has been fruitfully conjugated with commercially available antibiotic streptomycin to develop drug conjugated quantum dot (DCQ) for the improvement of drug efficacy. Furthermore the smartness of NS-GQD has also been investigated in terms of intracellular imaging and biocompatibility study. Different spectroscopic and microscopic analyses reveal the successful development of NS-GQD and DCQ. Therefore these findings demonstrate some astonishing capabilities of NS-GQD towards different real field applications.
