4. Conclusion
In conclusion, AgNPs were synthesized using an aqueous extract ofR. ribes leaves. The techniques of FT-IR, EDX, UV-Vis, XRD, TEM and FE-SEM AgNPs were applied for the nanoparticle’s characterization. The obtained results confirmed the green synthesis of silver nanoparticles with an average size of 26.11 nm and spherical morphology. The viability of malignant oral cell lines reduced dose-dependently in the presence of AgNPs. The IC50 of AgNPs were 220, 192, 174, 142, 125, 131, 250 and 219 µg/mL against HSC-2, HSC-3, HSC-4, KB, BHY, HN, OECM-1, and Ca9-22 cell lines, respectively.
