Sodium lauryl sulfate (SLS) is an important pollutant, it is urgent to develop simple and sensitive method for determination of SLS in environment. In this article, a gold nanoparticle (AuNP) sol with highly active surface enhanced Raman scattering (SERS) and good stability was prepared, based on the nanoenzyme AuNP catalysis of L-cysteine reduced HAuCl4. In the AuNP sol substrate containing the sensitized...
