摘要：

In this paper, a new magnetic interdigitated array (mIDA) has been designed, fabricated, and characterized for a magnetic bead separator on a plastic substrate, which can provide sampling capability in a low-cost disposable platform for magnetic bead-based biochemical detection systems. A mIDA was patterned and electroplated on a cyclic olefin copolymer (COC) substrate. To construct a magnetic bead sampler, an injection-molded microchannel layer on the COC was bonded over the mIDA using plastic thermal fusion bonding techniques. The microfabricated mIDA was excited using an external microelectromagnet to characterize the magnetic separator. Magnetic beads in a diameter of 2.0-9.0 mum were successfully separated over the mIDA from an aqueous solution with magnetic beads at a flow rate of 3.0-7.0 mul/min.
