Abstract

Carbon Quantum dots (CQDs) produced from sugarcane bagasse (SB) and sugarcane bagasse pith (SBP) were synthesized, by hydrothermal method. Analytical methods such as, UV–Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), Photoluminescence (PL), and high-resolution transmission electron microscopy (HR-TEM), were used to characterize the synthesized CQDs (SB and SBP). Furthermore, the anti-inflammatory and antioxidant properties of CQDs SB and SBP were assessed. The synthesized CQDs SB and SBP have spherical morphology, as shown by HRTEM investigation, and with a particle size of about 5 nm. Using the brine shrimp lethality assay, the toxicity of CQDs SB and SBP were investigated at various doses. Through their ability to scavenge H2O2 radicals, CQDs SB and SBP were studied with strong anti-inflammatory and antioxidant properties. This work sheds light on CQDs, which demonstrated powerful antioxidants and anti-inflammatory properties.
