The paper explores the use of nanoparticles of gamma Fe2O3 for hyperthermia treatment of living organisms by absorption of 1064 nm radiations from Nd:YAG laser. Escherichia coli cells have been used as the model system for demonstrating the effect wherein lysine is used as an interface between the cell walls and the nanoparticles. Scanning Electron Microscopic observations have, exclusively, proved that attachment of nanoparticles of iron oxide along with lysine alone is responsible for absorption of above radiations. The quantitative estimation has been provided by growth rate measurements and protein assessment of the cells. The nanoparticles of gamma Fe2O3 were synthesized by DC arc plasma assisted gas phase condensation.
