A method of preparing iron oxide nanoparticles using an herbal mixture comprising Capparis spinosa, Cichorium intybus, Solanum nigrum, Cassia occidentalis, Terminalia arjuna, Achillea millefolium, and Tamarix gallica. The method produces crystalline γ-Fe.sub.2O.sub.3 nanoparticles which are superparamagnetic. The iron oxide nanoparticles are used in a method of killing or inhibiting the growth of a bacteria and/or fungus, particularly in the form of a biofilm. The nanoparticles are also used in a method of treating colon cancer.
