“…[71] Development of electrochemical SPM (ECSPM) by coupling STM with electrochemistry brought substantial progress in surface and interface research. [72][73][74] In this setup, the bias potential of the STM tip and the sample can be separately controlled using a bipotentiostat. This allowed researchers to study surface reactions at the nanoscale and manipulate surface objects, as well as monitor oxidation-reduction conversion of the single molecule [66,75].…”

Tip-enhanced Raman spectroscopy (TERS) is a powerful technique that integrates the vibrational fingerprinting of Raman spectroscopy and the sub-nanometer resolution of scanning probe microscopy (SPM). As a result, TERS is capable of obtaining chemical maps of analyzed specimens with exceptional lateral resolution. This is extremely valuable for the study of interactions between molecules and substrates, in addition to structural characterization of biological objects, such as viruses and amyloid fibrils, 2D polymeric materials, and monitoring electrochemical and photo-catalytic processes. In this mini-review, we discuss the most significant advances of TERS, including: super high resolution chemical imaging, monitoring of catalytic processes, incorporation of pulsed-excitation techniques, single-site electrochemistry, biosensing, and art conservation. We begin with a short overview of TERS, comparing it with other surface analytical techniques, followed by an overview of recent developments and future applications in TERS.Graphical Abstract:

“…Scanning tunneling microscopy (STM) (1,2) has been finding growing application for in situ surface studies of various substrates immersed in solutions (3)(4)(5)(6)(7)(8)(9)(10)(11). Several reports have further demonstrated the possibility of performing the STM imaging under well-defined electrochemical environments, such as under potentiostatic control (12,13).…”

A design for a scanning tunneling microscope that is well suited for electrochemical investigations is presented. The construction of the microscope ensures that only the tunneling tip and the sample participate in electrochemical reactions. The design also allows rapid replacement of the tip or sample, and enables facile introduction of auxiliary electrodes for use in electrochemical experiments. The microscope utilizes stepper motor driven approach mechanics in order to achieve fully remote operation and to allow reproducible coarse control of tip/sample spacings for electrochemical experiments. Highly ordered pyrolytic graphite images at atomic resolution in air and aqueous solutions can be obtained with this microscope.
