Trapping and manipulation of individual nanoparticles in a planar Paul   trap
  Visualization and manipulation of nanoscale matter is one of the main and current challenges in nanosciences. To this aim, different techniques have been recently developed to non-invasively trap and manipulate nano-specimens, like nanoparticles or molecules. However, operating in air or vacuum still remains very challenging since most approaches are limited to a liquid environment. In this letter, we design and characterize a planar Paul trap optimized to trap and manipulate individual charged nanoparticles. This configuration offers competitive capabilities to manipulate nano-specimens in air or vacuum including in-plane integration, high trap confinement along with dynamical trap reconfiguration.
