Combining machine learning with surface-enhanced Raman scattering spectroscopy makes the analytical tool more powerful ...
A research team led by Dr. Huang Qing from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has ...
Raman scattering tends to be very weak, so one might not expect to be able to detect a signal from a single molecule; however, in the mid-1970s it was discovered that the Raman signal from certain ...
This unprecedented resolution resulted in a new methodology − scanning Raman picoscopy − that can structurally reconstruct a single molecule. Recently, in combination with electrical and force ...
SERS combines the specificity of Raman spectroscopy with the signal enhancement provided by the interaction between the molecule and the metal surface, enabling highly sensitive detection and ...
Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...
Researchers at Umeå University have recently developed a highly sensitive method for detecting bacterial spores — tough ...
