Abstract

In this paper, we found that ions in nanospace would be concentrated according to electric field gradient by using nanopillar array structures. Due to the ion-enrichment inside the nanopillar region, electroosmotic flow (EOF) in the nanopillar chip was suppressed dramatically. And also, we revealed that EOF suppression by ion-enrichment generated EOF profile deformation from a plug flow to an inverse parabolic flow.
