Hydrogels are cross-linked hydrophilic polymer networks that find application in biomedical and pharmaceutical industries due to their unique properties. Polyvinyl alcohol is a synthetic polymer, potential biomaterial blended with various materials and compounds, that can provide new options for drug delivery systems. Determination of photochemical properties of naproxen and tryptophan immobilized in polyvinyl alcohol and two other media: water and cyclohexane was performed using UV-Vis absorption and fluorescence methods. The influences of the media used on the spectral properties of naproxen and tryptophan have been shown. (original abstract)
