Summary: In this study, Ag-TiO2/ZIF-8 material with good environmental friendliness and biological antibacterial activity was prepared by solvothermal method. The structure and morphology of the synthesized material were characterized, and it was found that 20 wt.% Ag-TiO2/ZIF-8 had the best bacteriostatic effect on Escherichia coli and Bacillus subtilis under dark and UV conditions. The excellent antibacterial activity of Ag-TiO2/ZIF-8 is attributed to the synergistic effect of Ag-TiO2 and ZIF-8 under UV light.

Summary: The study identified Piper betle leaf ethanolic extract as having significant antibacterial activity against Staphylococcus aureus and Escherichia coli, inhibiting biofilm formation and promoting eradication. 4-Allyl-1,2-diacetoxybenzene and eugenol in the extract were found to play major roles in the antibacterial and anti-biofilm activity. These results suggest that ethanolic P. betle leaf extract shows promise as an alternative method for preventing bacterial diseases.
