Zinc oxide nanoparticles from flowers showed the potent antimicrobial and anticancer activity against the osteosarcoma MG-63 cells.

Osteosarcoma (OS) is a foremost mesenchymal bone neoplasm and it can occur at any age with survival rate is nearly 2-8 times lesser in elders than in teenagers. The clinical therapies for cancer treatment have gradually becoming outdated because of the developments of nano-medicine and multi-targeted drug-delivery. In this work, we green synthesized the zinc oxide nanoparticles from the flower (AS-ZnONPs) extract and evaluated its antimicrobial and anticancer potential against the OS MG-63 cells. The synthesized AS-ZnONPs were confirmed and characterized by using UV-vis spectroscopy, XRD, FE-SEM, and photoluminescence techniques. The antimicrobial activity of AS-ZnONPs was studied by disc diffusion technique. The viability of AS-ZnONPs treated MG-63 cells were examined by MTT assay. The apoptotic cells in the AS-ZnONPs treated MG-63 cells were assayed by dual staining. The MMP status of AS-ZnONPs treated cells were tested by Rh-123 staining. The cell adhesion assay was performed to detect the anticancer effects of AS-ZnONPs against MG-63 cells. The results of UV-vis spectroscopy, XRD, FE-SEM, and photoluminescence techniques proved the formation of AS-ZnONPs and it has the hexagonal wurtzite structures. AS-ZnONPs displayed the potent antimicrobial activity against the tested microbial strains. The AS-ZnONPs were appreciably inhibited the cell viability of MG-63 cells. The outcomes of fluorescence staining proved that AS-ZnONPs reduced the MMP and prompted the apoptosis in MG-63 cells. In conclusion, our discoveries demonstrated that the formulated AS-ZnONPs has the potent antimicrobial and anticancer activity against the MG-63 cells. The AS-ZnONPs could be potent chemotherapeutic agent in the future to treat the OS.
