Abstract
We analyzed a particle behavior of metal nanoparticles under electric field trapping by directly observing. Electric field trapping is the nanoparticles in the solution is collected toward narrow gap by dielectrophoresis force. We found that the nanoparticles are collected to bridging part, even after the particles are bridged over a narrow gap. Therefore, we fabricated gold wires with a narrow gap and measured diameter of particle cloud corresponding to applied voltage. The diameter of the particle cloud obviously increases as the applied voltage increases. We expect this phenomenon would enable to contribute to additional nanoparticle assembling which is useful for self-healing wire with high healing ability.
