ABSTRACT

This work represents a preliminary study about the Cytotoxicity of (non)magnetic nanoparticles. Antibiograms with nanostructured powder were performed. (Non)magnetic nanoparticles based on C-Fe, C-Cu, C-Al and C-C, were synthesized by plasma processing and analyzed with High-Resolution Transmission Electron Microscopy (HR-TEM). The difusimetric method was used to prove the bacteriostatic activity. This method is easy to perform and allows for obtaining of specific information related to germ sensitivity. Two reference germs were used: Staphylococcus Aureus ATCC 25923 and Escherichia Coli ATCC 25922. Comparing the inhibition zones, it was found that the cytotoxicity effect is related to (non)magnetic nanoparticles.
