【Abstract】 TB was employed as a reducing agent and protective agent to prepare the silver nanoparticles in alkaline media. The stable silver nanoparticles were obtained by adjusting different conditions including the ratio of TB and Na OH, and temperature. The diameter of Ag NPs obtained was about 5 ~ 40 nm. In addition, we used the silver nanoparticles as a colorimetric probe to investigate its colorimetric capacity towards L-Glutamic acid.更多还原
