Regulatory Parameters of Self-Healing Alginate Hydrogel Networks Prepared via Mussel-Inspired Dynamic Chemistry. Alegre-Requena, J. V.; Haering, M.; Herrera, R. P.; Diaz, D. New J. Chem., 2016, Accepted Manuscript. DOI: 10.1039/C6NJ02367C.

Abstract. Several key parameters that influence both self-healingabstract properties and water retention capacity of biohydrogel networks made of alginate-dopamine (Alg-DA) conjugates have been studied. A judicious combination of biopolymer concentration, dopamine content, pH-dependent cross-linking of catechol groups and Fe3+-coordination of the networks allowed control over the self-healing ability of these bioinspired materials. Moreover, the thixotropic nature of model hydrogels was confirmed by oscillatory rheological loop tests.
