Plasmon-Enhanced Spectroscopies with Shell-Isolated Nanoparticles

Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), due to its versatility, has been able to break the long-term limitations of the materialand substrate-specific generalities in the traditional field of surface-enhanced Raman spectroscopy. With a shell-isolated work principle, this method provides an opportunity to investigate successfully in surface, biological systems, energetic materials, and environmental sciences. Both the shell material and core morphology are being improved continuously to meet the requirements in diverse systems, such as the electrochemical studies at single crystal electrode surfaces, in situ monitoring of photoinduced reaction processes, practical applications in energy conversion and storage, inspections in food safety, and the surface-enhanced fluorescence. Predictably, the concept of shell-isolated nanoparticle-enhancement could be expanded to the wider range for the performance of plasmon-enhanced spectral modifications.
