چکیده
|
Two kinds of hydrogels were synthesized and made in contact with gold nanoparticles (aunps) in a colloidal solution to investigate their adsorption properties. these hydrogels were made either of the homopolymer poly(2-hydroxyethyl methacrylate) (phema) or the copolymer poly(2-hydroxyethyl methacrylate-co-2-hydroxyethyl acrylate [p(hema-co- hea)]. several compositions were used and the polymerization was induced by uv irradiation in the presence of the initiator darocur and the crosslinker 1,6-hexanediol diacrylate (hdda). aunps with a well defined dimension were synthesized by reduction of au(iii) salt solutions in the presence of tannic acid according to a procedure described in a previous work. the adsorption kinetics of the aunps on a [p(hema-co-hea)] hydrogel was monitored by uv-visible spectroscopy and the experimental data were well fitted with a sigmoidal function.
