Paper Abstract

Laser manipulation technique was applied to the patterning of single nano/microparticles in solution at room temperature. Individual gold nanoparticles were optically manipulated to the surface of a glass substrate in ethylene glycol. An ultraviolet laser beam was focused to the nanoparticle, which led to the transient temperature elevation of the particle, resulting in its photothermal fixation. A set of gold nanoparticles was aligned in the anisotropic optical potential well of a tightly focused laser beam with linear polarization and was adhered onto the substrate through the same photothermal method keeping their alignment. Combination of a microstereolithography with the laser trapping method enabled us to fabricate three-dimensional microstructures of resin and fix microparticles to them.
