A simple method for mitigating the toxicity of GQDs by embedding them in PEG matrix is reported here. The enhanced biocompatibility of polymer modified, P-GQDs, is attributed to reduced reactive oxygen species generation, as measured by an intracellular ROS assay. We also demonstrate the enhanced loading and efficient intracellular delivery of therapeutics by P-GQDs.</p>1 aChandra, Anil1 aDeshpande, Sonal1 aShinde, Dhanraj, B.1 aPillai, Vijayamohanan, K.1 aSingh, Neetu  uhttps://library.ncl.res.in/content/mitigating-cytotoxicity-graphene-quantum-dots-and-enhancing-their-applications-bioimaging-0
