Polymers that mimic chameleon skin

Biological tissues have complex mechanical properties -- soft-yet-strong, tough-yet-flexible -- that are difficult to reproduce using synthetic materials. An international team has managed to produce a biocompatible synthetic material that replicates tissue mechanics and alters color when it changes shape, like chameleon skin. These results, to which researchers from CNRS, Universite de Haute-Alsace(1) and ESRF, the European Synchrotron, have contributed with colleagues in the US (University of
