Caltech scientists have developed a comprehensive framework for designing metallo-polyelectrolyte complexes (MPECs), responsive gels with unique properties influenced by metal ions and polymer chains. These gels can change properties based on external stimuli like pH and ionic charge, making them suitable for advanced applications such as smart filters and artificial muscles. The research combines experimental work, computational modeling, and 3D printing to create a roadmap for customizing these materials at the molecular level for desired behaviors.
