Widening metal tolerance for hydrogels
Channel: MIT- MRL
Date: 18/12/2019

Inspired by mussel byssal threads, MIT graduate student Seth Cazzell shows a method to create a self-healing hydrogel in a wider range of metal concentrations through the use of competition, controlled by the pH of the environment in the lab of Associate Professor of Materials Science and Engineering Niels Holten-Andersen.
