Stable photo-reversible surface energy switching with azobenzene polyelectrolyte multilayers
Nasir M. Ahmad, Xiaoyu Lu and Christopher J. Barrett
Self-assembled multilayers of azobenzene polyelectrolytes produced a reversible change in surface energy that is stable over time, in a host material that is biocompatible for eventual applications of directed cell growth.
