Fluorescent Microscopy Investigation of Cytotoxic Impact on MCF-7 Cell Line Treated With Zinc Nanoparticles...

Zinc nanoparticles (ZnNPs) are a viable option in a number of disciplines, including cancer treatment, due to their special features. Among the several techniques for synthesizing ZnNP, biosynthesis with natural extracts is a highly effective and environmentally benign method, especially for uses in biomedicine. Using an aqueous extract of the marine red seaweed Jania rubens, we created a unique biosynthetic technique in this study to manufacture ZnNPs. The produced ZnNPs have a characteristic flower-like form, as seen by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effective production of ZnNPs and the involvement of biomolecules in the synthesis process were validated by energy-dispersive X-ray spectroscopy (EDAX) and Fourier transform infrared spectroscopy (FTIR) techniques. Using the MTT assay, the cytotoxic effects of the biosynthesized ZnNPs were evaluated, indicating their ability to inhibit MCF-7 breast cancer cells. Furthermore, ZnNPs' cytotoxicity against MCF-7 cells was validated by live/dead imaging experiments, which supported the MTT results.
