Melamine is a compound widely used in the industry that can be toxic for humans if consumed even in low concentrations. EC-SERS is an excellent alternative to classical methods to detect and quantify this compound because Raman spectroscopy provides a fingerprint of the molecules, providing very good sensitivity. In this work, timeresolved Raman spectroelectrochemistry is employed to generate a SERS substrate and to detect melamine, all in a single experiment. The dynamic character of this technique provides valuable information about the interaction of the molecule with the generated substrate. An optimization of the spectroelectrochemical method based on a multi-pulse amperometric detection has been performed. The new protocol presented in this work shows significant figures of merit in a very short experiment time, just 25 s. 1572-6657 http://hdl.handle.net/10259/7480 10.1016/j.jelechem.2022.116478 EC-SERS Gold-electrodes Time-resolved spectroelectrochemistry Raman Melamine Multiamperometric-SERS detection of melamine on gold screen-printed electrodes
