Metal-Binding Gels

From Biomacromolecules:

Self-Healing Mussel-Inspired Multi-pH-Responsive Hydrogels

Abstract Image
Another "bio-inspired" gel based on reversible catechol-iron binding.  Interestingly, they show that the best mechanical strength is obtained at pH ~9, which is apparently when the number of trifunctional crosslinks is maximized.
