This study suggests that minutes gold nanoparticles a good candidate as a medical application against cancer and need additional studies. Our results obtained a protocol for generation of highly stable AuNPs that had an average diameter of 5 nm generated by SW480 cell line after exposure to various concentrations of AuNPs were high than of cells treated by AuNPs. The results suggest AuNP is an effective system to reduce stress in cells. The devices used for the results of synthesizing the gold nanoparticles with or without coating by nano the effect of its concentration and the effect of Hydrogen Chloride or Hydrochloric acid (HAuCl4) and sodium chloride (NaCl) on the absorbance of surface plasmon resonance are: UV-visible spectroscopy, FTIR, Scanning Electron Microscope (SEM).
