Multiamperometric-SERS detection of melamine on gold screen-printed electrodes

A new, simple and fast protocol to generate gold-based SERS substrates is presented in this work. Melamine a compound widely used the industry that can be toxic for humans if consumed even low concentrations. EC-SERS an excellent alternative classical methods detect quantify because Raman spectroscopy provides fingerprint of molecules, providing very good sensitivity. In work, time-resolved spectroelectrochemistry employed substrate melamine, all single experiment. The dynamic character technique valuable information about interaction molecule with generated substrate. An optimization spectroelectrochemical method based on multi-pulse amperometric detection has been performed. new work shows significant figures merit short experiment time, just 25 s.
