Silver in modern life, such as medicine, drinking water disinfection has a wide range of applications, a large number of silver released into the natural environment, the microorganisms in the fish in the water and environmental damage based on the literature using the method of thermal water with bovine serum albumin as reductant synthesis of bovine serum albumin protect the shower of gold nanoparticles as probes, set up a colorimetric sensors used for rapid detection of silver ions This fluorescence probe has a good selectivity toward silver ions and a good linear relationship between 0.1 and 10 nM(R2=0.98746). A detection limit of sliver ions is 0.1 mM.
