A dumbbell-liked organ-metal composite was prepared with wet chemistry. Then the solution was subjected to AC e-field. Herein, three types of electrodes configuration were adopted to align the colloids. Theoretically, quasi one-dimensional structures should be observed, and it was the case in the third configuration. SEM, AFM and TEM were utilized to characterize the resultant morphology. The mechanism was described with dielectrophoresis theory.
