TL;DR: In this paper, the authors survey the fundamental principles, advantages and limitations of using localized surface plasmon resonance to enhance the Raman signal in PERS and provide an overview of state-of-the-art PERS applications in materials characterization, bioanalysis and the study of surfaces and interfaces.

TL;DR: An electrochemical tip-enhanced Raman spectroscopy by introduction of the light horizontally to the EC-STM cell to minimize the optical distortion and to keep the TERS measurement under a well-controlled condition will open a new era for using EC-TERS as an important nanospectroscopy tool for the molecular level and nanoscale analysis of some important electrochemical systems.

TL;DR: This work focuses on the progress of TERS for studying the surfaces and interfaces under different conditions, from ambient, to UHV, solid-liquid and electrochemical environments, followed by a brief introduction to the current understanding of the unprecedented high spatial resolution and surface selection rules.

TL;DR: A facile chemical method to prepare shell-isolated Ag nanoparticle/tip is reported, which features an alternative plasmon-mediated photocatalysis pathway by smartly blocking "hot" electrons and offers a unique way for the promotion of ultrahigh sensitivity and reliability in plAsmon-enhanced spectroscopies.

TL;DR: This review focuses on the tip-related issues in TERS, and discusses the parameters that influence the enhancement and spatial resolution of TERS and the possibility to optimize the performance of a TERS system via an in-depth understanding of the enhancement mechanism.
