摘要: An electrode-rail dielectrophoretic (DEP) assembly effect for microparticle pearl-chain formation is reported. Under this effect, single curvilinear particle chains are formed along spiral strip electrodes in a microfluidic device actuated by alternating signals. Moreover, the snaking traveling movement of entire individual curving pearl chain electrode also observed. The could be mainly interpreted specific distribution electric field above microelectrode array. Further, inter-attracting DEP force between neighboring particles generated when originally uniform strongly perturbed due to existence themselves. chain’s rationalized non-ignorable ohmic resistance electrodes, which leads nonuniformity strength and elongation direction.
