Notes:
Iron oxide and its hydrate nanoparticles were synthesized by hydrothermal method andconfirmed by infrared and SEM (Scanning Electron Microscope) et al. The dimensions of thenanoparticles are about 50-120 nm. The crystalline form of iron oxide nanoparticles is likeglobosity while its hydrate rod. Amino acids intermingling with the synthesized nanoparticles werecrystallized to investigate the space effect of the nanoparticles. The crystalline forms of crystal aredifferent to that of pure amino acid. The positions and width of the nanoparticles’ peaks in theinfrared spectrum are changed too. Microscope observation and infrared spectrum results indicatedthe nanoparticles had changed the internal structure of amino acids crystal. To considerate thetoxicity of the synthesized nanoparticles, MTT (3-(4,5-dimethylthiazol 2-yl)-2,5diphenyltetrazolium bromide) assay was used to determine their cytotoxicity. The OD value(Optical Density) was used to calculated RGR% (Relative Generation Rate) of cells, whichdetermined the grade of cytotoxicity. The RGR of nanoparticles of iron oxide and its hydrate areabout 1 to 2, which indicate they have just low toxicity
