| Outline of Final Research Achievements |
A gel assembly was formed via metal-ligand interactions using polyacrylamide modified with iron-porphyrin (Fe-Por) and L-histidine (L-His) moieties. The Fe-Por gel and the L-His gel immediately adhere to each other upon agitation in an 80 mM Tris-acetate buffer (pH 9.0). The assembly of the Fe-Por gel with L-His gel showed a pH dependency. The L-His gel formed an assembly with the Fe-Por gel at pH 9.0, however, no assembly of gels was observed at pH 2.0. Agitation in an aqueous solution containing an 60 mM L-His causes the assembly of the Fe-Por gel and L-His gel to dissociate, then washing with a fresh buffer reassembles the gel pieces. The binding and dissociation of the Fe-Por gel with the L-His gel are found to be reversible.
