文摘

The detail SERS mechanisms of EC are presented by the ab initio calculation combined with the discrete dipole approximation method. The surface enhancement factor can be 3.6 × 1010 while regarding it as a product of both chemical and electromagnetic enhancement effect. We are absorbed in studying a sensitive method (SERS) to detect Ethyl Carbamate which is probably carcinogenic to humans.
