Abstract
The continuing rush for potential biomedical applications has sparked the fabrication of graphene quantum dots (GQDs) particularly from agricultural waste. GQDs are unique among carbon-based nanomaterials due to their flexibility, chemical stability, size control, and non-toxic nature. In this study, we have developed Graphene Quantum dots from sugarcane bagasse (GQDs-SB) and sugarcane bagasse pith (GQDs-SBP) by carbonization followed by microwave pyrolysis. The optical properties of the synthesized GQDs-SB and GQDs-SBP were characterized by Ultraviolet–Visible spectroscopy and Photoluminescence (PL) analysis and the surface functional groups were determined by FT- IR analysis. The High resolution transmission electron microscopy (HR-TEM) was used to examine dimensions and structure of GQDs-SB and GQDs-SBP. The storage stability of GQDs-SB and GQDs-SBP was monitored using Ultraviolet–Visible spectroscopy. The synthesized GQDs-SB and GQDs-SBP were evaluated for biological applications like anti-oxidant activity, anti inflammatory activity and cytotoxic effect was also assessed. GQDs-SB and GQDs-SBP demonstrated significant antioxidant and anti-inflammatory effects due to their great ability to scavenge free radicals and extraordinary water solubility. The synthesized GQDs-SB and GQDs-SBP were less toxic in nature.
