In this research, a zinc oxide nanorods material was synthesized by the chemical bath deposition method and the zinc oxide material was a wide band gap semiconductor so the absorbance of zinc oxide is in the UV light region. The effect of surface plasmon resonance (SPR) form gold nanoparticles, it can enhance the absorbance of the visible light. The arginine molecular is one of the chiral molecule and focus on the optical property. The characteristics of the material can be measured by a different of analysis like the XRD、SEM、TEM、UV-vis、Spin polarization etc. From the result, it could find that the Au nanoparticles successfully synthesized by the simple method. The gold nanoparticles enhance the absorbance light to visible and the SPR effect the visible peak in different shape of gold nanoparticles such as gold nanoparticles and the urchin gold nanoparticles. In the spin polarization system, we created the different angular moment light such as spin up and spin down. The arginine molecular under the spin polarization system measurement, the result that the different spin light source could enhance by the different type of arginine molecular. The gold nanoparticles also helped the arginine molecular to increase the result of the select.
