Several different methods for patterning colloidal particles arrays have emerged in the recent past, including surface chemistry, electrostatic, and surface tension driven assembly. In contrast with other methods, magnetic template driven assembly of colloidal particles can offer significant advantages. In particular, the ability to generate repulsive forces opens the possibility for assembling particle arrays with controlled defects. Magnetic template based assembly of superparamagnetic colloidal particles has been studied both theoretically and experimentally. Experimental investigations reported here have used an array of ferromagnetic islands, fabricated through conventional photolithographic lift-off process, to attract magnetic beads from colloidal suspension
