Alice Sandra Buteicǎ, Dan Eduard Mihaiescu, Alexandru Mihai Grumezescu, Bogdan Stefan Vasile, Alexandru Popescu, Oana Maria Mihaiescu, Roridca Cristescu: The anti-bacterial activity of magnetic nanofluid: Fe3O4 / oleic acid / cephalosporins – core/shell/adsorbtion-shell proved on S. aureus and E. coli and possible applications as drug delivery systems. Digest Journal of Nanomaterials and Biostructures, 5(4):927-932, 2010.
Using this system as active compound carrier, the anti-bacterial activity of the Fe3O4/oleic acid/cephalosporins nanoparticles (core/shell/adsorption-shell) on S. aureus and E. coli was tested. The dimensions of Fe3O4 nanoparticles were in the 5-20 nm range and they were characterized by High Resolution Transmision Electron Microscopy. The antibacterial activity was observed in both, reference Fe3O4/oleic acid shell nanoparticles and adsorption shell cephalosporins case. These nanofluids may be used in drug delivery systems.
