UV–visible spectroscopy is based on the measurement of the ratio of the passed light with respect to the incident light in the wavelength range from the UV to the visible. Theadsorption of proteinson the surface of theNPsinduces changes on theabsorption spectrum, which makes this method a fas...

Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared (NIR)) ranges. The ab...
