What is Surface-Enhanced Raman Scattering (SERS)? Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that significantly enhances the Raman scattering signal of molecules ...

Surface-enhanced Raman spectroscopy is a highly sensitive molecule characterization method, significantly more sensitive than ordinary Raman spectroscopy due to the excitation of Raman modes matching ...

The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...

Using the shrink-assembled liquid 3D hot spot matrix as a microreactor, a new method for quantitative detection of blood drug concentration by surface-enhanced Raman spectroscopy (SERS) was ...

The global development of civilization diseases is a challenge that requires many modern solutions, not only in terms of treatment, but first and foremost in terms of early diagnostics. One of the ...

Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables.

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240260 discusses a novel strategy for detecting trace-level nanoplastics in aquatic environments. Plastic materials have ...

The current focus for disease management against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is vaccination. However, rapid diagnosis of variants is still pivotal for public health ...

SERS offers a greater signal-to-noise ratio than ordinary Raman spectroscopy, so it is useful in single-molecule detection or detecting analytes in low concentrations. Improvement of the spectroscopic ...
