The photophysics of Gum Arabic in aqueous solutions is an area of research that explores the fluorescence and absorption properties of this natural polymer. In this book, authors explore how different pH values and the presence of urea derivatives, amide derivatives, and guanidine hydrochloride affect the photophysical properties of Gum Arabic. The research employs a range of analytical techniques, including fluorescence, absorption, time-resolved, and excitation spectroscopy to investigate the changes in the fluorescence and absorption spectra. The Stokes shift, quenching, photobleaching, Förster Resonance Energy Transfer, and solvent effects are also studied. The results of the work, suggest that pH and the presence of urea derivatives, amide derivatives, and guanidine hydrochloride influence the conformational changes in Gum Arabic, which in turn affects its photophysical properties. The work also explores the protein folding and stability of Gum Arabic, including the hydrophobic, hydrogen bonding, electrostatic and van der Waals interactions that influence its structure. This investigate has broad implications in various fields, including food science, cosmetics, and drug delivery. The biodegradable nature of Gum Arabic makes it a sustainable and renewable resource for the development of hydrogels and other biomedical applications. The study of the optical properties of Gum Arabic can also contribute to the development of sustainable and green chemistry practices in various fields. The research also explores the surface chemistry and interfacial properties of Gum Arabic, which can have implications for the development of rheology modifiers and other functional materials.
