Stuck fast : The covalent immobilization of polymeric single molecules is achieved by the photochemically induced CH/NH insertion reaction of perfluorophenylazides (see picture). When the concentration of the surface azido groups is decreased, isolated polymeric single molecules are observed. This technique is especially suited for materials that do not possess functional groups and are difficult to be immobilized by other means.
