What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Typically, WGM microresonator sensors employ the reactive mechanism 27 to detect the binding of a single unlabelled biomolecule at the resonator surface 1,2,3. Molecular signals are observed as ...

Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...
