We proposed the fabrication of gold micro-electrode and grating electrode through laser assembling of gold nanoparticles and realized the electrical interconnection of the single carbon nanotube and gold nanolines, which can decrease the damage of the functional unit to a great extent. This method can also solve the problem of inadequate mass transport in the fabrication of ions. The microstructure could keep unoxidized in the atomasphere with excellent continuity, integrity, and electrical properties, which made this technique have wide application prospects.
