UV-visible (UV-vis) spectroscopy and diffuse reflectance spectroscopy (DRS) are very effective analytical methods that have broad applications in many scientific and commercial disciplines. This chapter aims to provide a brief and comprehensive description of the fundamental concepts, equipment, and uses...
3.5UV–visible spectroscopy 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, whic...
