Introduction

Protein–polymer conjugates are widely employed for applications in medicine, biotechnology and nanotechnology. Covalent attachment of synthetic polymers to proteins improves protein stability, solubility, and biocompatibility. Furthermore, synthetic polymers impart new properties such as self assembly and phase behavior. Protein–polymer conjugates display a unique combination of properties derived from both the biologic and synthetic materials, which can be individually tuned to elicit a desired effect.

Principle

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference or blank sample. This property is influenced by the sample composition, potentially providing information on what is in the sample and at what concentration. The only requirement is that the sample absorb in the UV-Vis region, i.e. be a chromophore. Absorption spectroscopy is complementary to fluorescence spectroscopy. Parameters of interest, besides the wavelength of measurement, are absorbance (A) or transmittance (%T) or reflectance (%R), and its change with time.

Applications

UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of diverse analytes or sample, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied.
