A technique for judging whether a common mineral formed through biological activity could aid the search for ancient life on ...

At its simplest, Raman spectroscopy is a light-scattering technique. When monochromatic light, usually from a laser, hits a sample, most of it returns unchanged. But a small portion scatters ...

Raman spectroscopy enables real-time bioreactor monitoring of glucose and lactate without breaching the sterile boundary.

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

Utilizing SERS for protein detection offers high sensitivity and label-free analysis, advancing proteomics and biomarker ...

Fluorescence spectroscopy has great sensitivity, allowing scientists to detect signals from single molecules. But it has limited chemical specificity, making it hard sometimes for researchers to ...

Surface-enhanced Raman spectroscopy (SERS) has been increasingly popular in analytical chemistry. Recognized for its molecular specificity, rapid ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
