Exploring catalytic efficacy and anti-bacterial performance with molecular docking analysis of g-C₃N₄-grafted-Ag doped SnO₂ QDs

The current work demonstrates the controlled synthesis of graphitic carbon nitride grafted silver (g-C₃N₄-g-Ag) doped tin oxide (SnO₂) quantum dots (QDs) using the co-precipitation method. This research aimed to decrease the charge recombination rate of SnO₂ and enhance their multifunctional effectiveness as catalysts and antibacterial agents with molecular docking analysis. The doping of g-C₃N₄-g-Ag increased the charge separation efficacy and number of active sites, resulting in the enhancement of catalytic and antibacterial activities. 6 mL of g-C₃N₄-g-Ag doped SnO₂ QDs indicated remarkable dye removal activity of over 97.7%, which signifies its potential application in various environmental settings. Furthermore, the doped QDs demonstrated the 4.05 ± 0.08 mm inhibition area contrary to multiple drug resistant (MDR) Staphylococcus aureus (S. aureus). The inhibitory effect of g-C₃N₄-g-Ag doped SnO₂ QDs on DNA gyrase_{S. aureus} and tyrosyl-tRNA synthetase_{S. aureus} was elucidated using molecular docking analysis, supporting their bactericidal activity.
