Green synthesis spinel ferrite nanosheets and their cytotoxicity and antibacterial activity

Spinel ferrite nanosheets have attracted particular attention in medical and applied sciences due to their high magnetic and flexible properties and biocompatibility. In this study, ferrite-spinel nanosheets were synthesized using Nepeta bornmuelleri. This synthesis method is a potentially low-cost and environmentally friendly method. The physicochemical properties of the synthesized nanosheets were determined using X-ray diffraction (XRD), scanning electron microscopy (SEM), and scanning electron microscopy (TEM). The functional groups present in the plant extract, which are possibly responsible for the synthesis of nanosheets, were determined by Fourier transform infrared spectroscopy (FTIR). The results showed that the nanosheets have a size in the range of less than 100 nm. Cytotoxicity and antibacterial activity of produced nanosheets were studied. The effect of cytotoxicity of spinel ferrite nanosheets on rat cells was evaluated. Spinel ferrite nanosheets are toxic. The results of antimicrobial tests showed that Streptococcus mutants, Escherichia coli, and Pseudomonas aeruginosa were sensitive to the concentration of 25-50 mu g/mL of spinel ferrite nanosheets. Spinel ferrite nanosheets have an antimicrobial effect on these pathogenic pathogens. The anticancer effect of synthesized nanoparticles showed that increasing the concentration of nanosheets decreased the survival rate of cancer cells, which indicated the direct interaction effect of the dose on the inhibition rate of nanosheets.
