Researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. A team headed by Ludwik Leibler, involving researchers from the Laboratoire Matière Molle et Chimie (CNRS/ESPCI ParisTech) and the Laboratoire Physico-Chimie des Polymères et Milieux Dispersés (CNRS/ UPMC/ESPCI ParisTech), has succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles.
