Abstract | Au nanorods (Au NRs) modified by glutathione (GSH) were prepared. Based on the dependence of localized surface plasmon resonance (LSPR) peak shift on their arrangement, the structure and optical properties of GSH-modified Au NRs was studied at different pH conditions. At pH=5, some metal ions were chosen to detect the effect of their interaction with GSH-Au NRs on the LSPR peak of Au NRs. The results demonstrate that Cu2+ can obviously induce red shift of LSPR peak comparing with other metal ions. The reason is the rearrangement of Au NRs induced by Cu2+. Meanwhile, the photothermal experiment for pure Au NRs and GSH-Au NRs with copper ions were carried out to detect the effect of copper ions on optical properties of Au NRs. Comparing with pure Au NRs, GSH-Au NRs with copper ions decreased the efficiency of phothothermal conversion. During photothermalcoversion process, copper maybe capture the electron of Au NRs and decrease the efficiency of nonirradiation. So, Au NRs modified by GSH show the selective detection for Cu2+. The results here maybe provide a new method for detection of heavy metal ions. |
