26. Several other Raman spectroscopies have been developed, including tip-enhanced Raman spectroscopy (TERS)27,28,29,30, shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS)31, and surface-enhanced nonlinear spectroscopies
Surface-enhanced Raman scattering (SERS) is a very promising tool for the direct detection of biomarkers for the diagnosis of i.e., cancer and pathogens. Yet, current SERS strategies are hampered by non-specific interactions with co-existing substances in the biological matrices and the difficulti...
We speculated that surface enhanced Raman spectroscopy (SERS) might be an ideal technique for detecting the sxRNA bound protein with a high degree of sensitivity and specificity. With this long-term goal in mind, we first developed the two-step process described here for the simple detection of...
The size, shape, and composition of Ag as well as their optical properties were studied by extinction spectroscopy, hyperspectral dark field microscopy, transmission and scanning electron microscopy (TEM and SEM), and energy dispersive X-ray spectroscopy (EDX). Finally, the surface-enhanced Raman ...

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive technique that enhances the Raman scattering of molecules supported by some nanostructured materials. SERS allows for the structural fingerprinting of low-concentration analytes through the plasmon-mediated amplification of electrical fields or ...
UV irradiation of aligned diphenylalanine peptide nanotubes (FF-PNTs) decorated with plasmonic silver nanoparticles (Ag NPs) enables photo-induced surface-enhanced Raman spectroscopy. UV-induced charge transfer facilitates a chemical enhancement that pro
