Abstract

The demand for on-site analyses has been accelerated recently. In this work, a new on-site device was developed by combining an electroosmotic pump (EOP) and a molecularly imprinted absorbent. We investigated the effects of the structural factors on the performance of EOPs by using a microfabricated structure array. The EOP with the optimum microstructure array generated 830 Pa, which was high enough to flush liquid though the absorbent. For a molecularly selective separation, molecular imprinting was adopted to form the recognition site for 4-(tributylammoniummethyl) benzyl tributylammonium chloride (TBTA) on the surface of the EOP. The surface of the modified EOP showed selective separation ability to TBTA.
