Supramolecular velcro unzipped by a voltage

Scientists in China have designed a velcro-like material held together by non-covalent interactions that can be unfastened by electrical means and refastened again under pressure. This video shows the velcro holding a 100g weight with (left) and without applied voltage (right). Taken from the following paper: J Guo et al, Chem. Sci., 2014, DOI: () Read more at:
