In recent years, surface-enhanced Raman scattering (SERS) spectroscopy has gained recognition as a powerful tool for chemical analysis and for determining structural information about molecular systems in a wide range of fields. The emerging applications in the biomedical sciences include the chemical characterisation of biomarkers, diagnostic immunoassays for disease detection and non-invasive cellular and tissue imaging. The SERS effect and mechanism is based on the strong amplification of the Raman signals of target molecules adsorbed and/or in proximity with Au or Ag metallic nanostructures and plasmonic quantum dots, which are commonly utilised in colloidal form or supported on solid substrates. The degree of SERS amplification is greatly dependent on the substrates employed for qualitative analysis and quantitative detection. Therefore, the development of SERS technologies with high sensitivity, reproducible results, and stability has become a hot topic in recent years, particularly as a clinical tool in the biomedical fields.
Interestingly, innovations in Raman instrumentation have played a role in the rapid development of SERS and related concepts. These technological advances include confocal Raman microscopy (CRM), spatially offset Raman scattering (SORS), tip-enhanced Raman scattering spectroscopy (TERS), and surface-enhanced Raman chemical imaging (SER-CI).
For this Special Issue, we welcome original research papers as well as reviews on current developments in the design of high-sensitivity and reproducible biomedical diagnostic systems with SERS, TERS, CRM, and/or SORS technologies. This includes the design of state-of-the art biosensors for disease biomarkers, characterisation of biomolecules, biological analysis, and medical diagnostics. Theoretical research on the interaction and spatial distribution of adsorbate biomaterials on metal surfaces and substrates is also encouraged. The design and development of lab-on-a-chip devices, wearable and plug-and-play biosensors, and portable/handheld SERS-based platforms for point-of-care applications is of special interest. Reviews should provide an in-depth examination of the most recent research in a specific context or discuss the existing and future issues related with SERS and Raman imaging in the biomedical field.
