title: Clean and modified substrates for direct detection of living cells by surface-enhanced Raman spectroscopy.
abstract: Iodide adsorption and electrochemical negative potential desorption were proposed and compared to obtain clean SERS substrates. The two methods can effectively eliminate the interference of surface impurities in the SERS detection. SERS signals of membranes of living cells with a good reproducibility have been obtained.
