“…The technique, termed shell-isolated nanoparticle-enhanced Raman spectroscopy, or SHINERS, has dramatically expanded the practical application of SERS, enabling measurements on effectively any substrate due to the minimal interference of the 'SHIN' resonators [82][83][84]. Procedures to synthesise SHINs are now well-documented [85], typical particles comprising a 55-120 nm spherical gold or silver core [82,86,87] [92], graphene [93,94] and other carbon materials [95,96]. Example core-shell particles are depicted in Figure 5 The substrate generality of SHINERS has greatly benefitted electrochemical Raman spectroscopy and an impressive range of native electrode substrates have been investigated including Ag [97,98], Au [99][100][101][102][103][104], Pt [99,102], Pd [102], Rh [105], Ni alloys [106,107], Cu [108] and glassy carbon (GC) [102].…”

Electrochemical interfaces are ubiquitous, and characterisation tools that allow us to interrogate them on the molecular scale underpin a wide range of technologies. Because of their dynamic nature, in situ or operando measurement is often necessary, and the coupling of electrochemical techniques with spectroscopic methods is a powerful solution to this challenge. Vibrational spectroscopy in particular can provide important insights into the chemical nature of species adsorbed at electrode surfaces. When combined with electrochemistry, the influence of a potential perturbation to the interface can be studied, helping to build a complete picture of molecular processes in complex electrochemical systems. Here, we review the latest advances in vibrational spectroscopy at electrochemical interfaces, with a focus on surfaceenhanced approaches including surface-enhanced Raman scattering, shell-isolated nanoparticle-enhanced Raman spectroscopy, tip-enhanced Raman spectroscopy and surface-enhanced infrared absorption spectroscopy.

“…To form carbon shells, Yang et al deposited p-mercaptobenzoic acid on the surface of silver nanoparticles and then carbonized the deposited organic layer in a concentrated solution of sulphuric acid. TEM analysis of the nanostructures obtained showed that, after this procedure, the silver cores are covered by a carbon layer with a thickness of about 2 nm (Yang et al, 2011). SHINERS nanoresonators protected by a layer of polydopamine have been synthesized by Ye et al (2017).…”

In 2010, Tian et al. reported the development of a new, relatively sensitive method of the chemical analysis of various surfaces, including buried interfaces (for example the surfaces of solid samples in a high-pressure gas or a liquid), which makes it possible to analyze various biological samples in situ . They called their method shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS). SHINERS spectroscopy is a type of surface-enhanced Raman spectroscopy (SERS) in which an increase in the efficiency of the Raman scattering is induced by plasmonic nanoparticles acting as electromagnetic resonators that locally significantly enhance the electric field of the incident electromagnetic radiation. In the case of SHINERS measurements, the plasmonic nanoparticles are covered by a very thin transparent protective layer (formed, for example, from various oxides such as SiO 2 , MnO 2 , TiO 2 , or organic polymers) that does not significantly damp surface electromagnetic enhancement, but does separate the nanoparticles from direct contact with the probed material and keeps them from agglomerating. Preventing direct contact between the metal plasmonic structures and the analyzed samples is especially important when biological samples are investigated, because direct interaction between the metal nanoparticles and various biological molecules (e.g., peptides) may lead to a change in the structure of those biomolecules. In this mini-review, the state of the art of SHINERS spectroscopy is briefly described.

“…Hence, considerable efforts have been focused on the development of carbon or graphene SHINs. Yang et al have prepared ultrathin carbon‐shell‐isolated Ag nanoparticles by carbonization ( Figure a) . They modified 4‐mercaptobenzoic acid molecules on the Ag nanoparticle surface via the formation of an Ag–S bond through the adsorption of cetyltrimethylammonium bromide (CTAB) on Ag nanoparticles via electrostatic interaction.…”

Shell‐isolated nanoparticles (SHINs) composed of a protective shell and a plasmonic metal core have been extensively used in plasmon‐enhanced Raman and fluorescence spectroscopy. Whereby, SHIN‐enhanced Raman spectroscopy has effectively overcome the material and morphology limitations for traditional surface‐enhanced Raman spectroscopy and demonstrates advanced properties in various fields including surface science, chemical analysis, biological and medical assays, and material science. Meanwhile, the fluorescence of the optical species can be enhanced smartly by SHINs due to the localized surface‐plasmon resonance effect of the SHINs, the so called SHIN‐enhanced fluorescence. In this review, the synthesis of the SHINs is discussed according to the shell materials. Then, the developments and advancements in application of the SHINs in Raman and fluorescence spectroscopies are comprehensively described. Finally, potential future developments for SHINs and SHIN‐enhanced spectroscopy are presented.
