Gold-silver alloy on SERS substrates detects trace level explosives and pesticides Ocean Optics has introduced a new substrate for Raman spectroscopy applications. The new RAM-SERS-SP Surface Enhanced ...

Thorlabs is pleased to announce the release of a Surface-Enhanced Raman Spectroscopy (SERS) Substrate. Based on its proprietary textured surface technology, SERS in a non-destructive, highly sensitive ...

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 ...

An interview with Renee Frontiera from the University of Minnesota, discussing the development of a super-resolution Raman microscope that could one day supersede fluorescence-based super-resolution ...

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 ...

Breweries typically monitor fermentation by analyzing broth composition. Alcohols, esters, acids and residual sugars are ...

In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.210048, the research group of Professor Venugopal Rao Soma from the University of Hyderabad, India, discuss recent advances in ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

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 ...

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 ...
