Given'the slowest rates of drug release, the color modification of the doxycycline/gelatin solution and the increase of viscosity of the gelatin solution in presence of doxycycline, it can be assumed that strong physical interactions (because GPC analyzes did not confirm the increase of the average molar masses of gelatin treated with doxycycline) take place between the doxycycline chromophore groups and the functional groups of the gelatin.
These copolymers contain azide and alkyne groups as well as the chromophore groups. Heating induces crosslinking by 1,3 dipolar cycloaddition between an azide and an alkyne to give a 1,3 triazole linkage, resulting in a very stable structure.
PAs chain contains two types of chromophore groups being in conjugation: the aromatic ring and the imine (C=N) group.
