Shell‐Isolated Nanoparticle‐Enhanced Raman Spectroscopy at Single‐Crystal Electrode Surfaces

As an innovative technique, shell‐isolated nanoparticle‐enhanced Raman spectroscopy (SHINERS) eliminates the material and morphology generality problems of surface‐enhanced Raman spectroscopy (SERS). For the past few years, SHINERS has been extensively employed in many fields, especially in the electrochemistry field. This article renders a brief overview of the developments of SHINERS technique and its applications in electrochemistry. First, we clearly explain the basic principles of the SHINERS technique, such as design principles, materials synthesis, characterization methods, and related theoretical calculation methods. We then describe about the significant applications of electrochemical SHINERS (EC‐SHINERS) with a focus of study on various single‐crystal electrode surfaces. Finally, we summarize the recent developments and give an outlook for future developments in the SHINERS field.
