Polyelectrolytes with opposite charges associate into complexes or coacervates. As thin films, these complexes control surface properties including bioadhesion. Coacervates, found in nature as membraneless organelles in cells, are held together by multiple “sticky” charge-charge interactions. This special type of attraction can be moderated by salt (“saloplasticity”) providing unprecedented control over the materials properties of this fascinating form of amorphous condensed matter.
