Can capillary forces be exploited to operate a carbon nanotube as a nanopipette? The withdrawal of a metal nanoparticle from a carbon nanotube is observed by electron microscopy. The process depends on the meniscus pressure and on the Laplace pressures of the nanoparticle and a larger droplet adjacent to the open end of the tube.
