Sažetak
Enhanced Raman signal from the gelling molecule, bis-(S-phenylalanine) oxalyl amide, adsorbed on the silver nanoparticles entrapped in gel allowed a study of the molecular self-assembly in the nanoparticle-hydrogel composite. Changes in intensity of the amide II bands caused by temperature and concentration increase imply involvement of the hydrogen bonds between the oxalyl amide groups in gelation process. At the same time band intensity regarding the benzene ring vibration modes remained unaffected, indicating strong adsorption of the gelator molecules through the phenyl moieties to the nanoparticles in both, citrate and borohydride, silver colloid hydrogels.
