摘要

In this work, we report the green synthesis of fluorescent carbon dots (MS-CDs) from Mammea suriga leaves via a simple and efficient probe for environmental detoxification. The synthesized MS-CDs were spectroscopically characterized by UV–Vis spectroscopy, fluorescence spectroscopy, FTIR, HR-TEM, X-ray diffraction, and 13C NMR spectroscopy. The particle sizes were found to be in the range of 2.2–4.6 nm. FTIR analysis confirmed the presence of -OH functional groups, and XRD studies confirmed the amorphous nature of the MS-CDs. The synthesized MS-CDs were used as a photocatalyst in the degradation of Eosin B, exhibiting 90% and 68% degradation activity at pH 6 and pH 9, respectively, within 240 min. Furthermore, the biological studies reflected that the MS-CDs are a promising scaffold owing to their excellent antioxidant and anti-inflammatory properties with IC50 values as 42.92 ± 0.92 and 34.00 ± 0.98 µg/mL respectively. Additionally, MS-CDS exhibited significant antidiabetic potency with IC50 value as 33.57 ± 0.73 and 25.78 ± 0.51 µg/mL for α-amylase and α-glucosidase inhibition, respectively. This study highlights MS-CDs as promising dual-function materials, combining efficient photocatalytic performance with potent biological activities.
