We have developed magnetically controllable gold nanoparticles by synthesizing superparamagnetic <TEX>$Fe_3O_4$</TEX> core/gold shell nanoparticles. The core/shell particles the capability of forming 1D chains in presence an external magnetic field. Here we demonstrate dynamic and reversible self-assembly chain structures aqueous solution without any templates or physical chemical attachment. spatial configuration can be arbitrarily manipulated controlling direction a This technique provide arbitrary manipulation for fabrication purpose. To this capability, present immobilization particle on glass substrate.
