Gold Microshell Tip for In Situ Electrochemical Raman Spectroscopy
Tip fabrication by a new strategy is proposed for simultaneous acquisition of electrochemical (EC) signals from an ultramicroelectrode and spectroscopic information from surface-enhanced Raman scattering (SERS). The EC-SERS tip (see figure) is prepared by carefully tuning a SERS-active gold microshell to maximize Raman scattering, mechanically attaching it to the end of a micropipet, and electrically connecting it to a ruthenium inner layer through electroless deposition.
