Abstract
A monopole probe and a dipole probe are introduced for one-by-one manipulation of fine particles. The holding force of a particle is controlled by an external power supply. The monopole probe is a tungsten needle, and it can manipulate conducting particles on a metal substrate by applying voltage between the probe and the substrate. It is also capable of welding metal particles on the substrate using it as an electrode. The dipole probe consists of two electrodes, and traps fine particles for any combination of materials of particle and substrate. Both probes can manipulate particles larger than 30μm, which cannot be done by the conventional needle-like probes.
