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 ...

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 ...

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 ...

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 ...

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 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 ...

Light-matter interaction is one of the most fundamental ways to explore the physical world. While the reflection and refraction of light reveal the structural characteristics of matter, inelastic ...

Lipid oxidation is a significant issue for the meat industry. This is because lipid oxidation can have a detrimental impact on not only sensory quality, in terms of odor and flavor, but it can also ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...
