Abstract

In this study, we developed a nanoparticle concentrator chip which can extract concentrated nanoparticle solution from the outlet relying on fluidic force, alternating-current electroosmosis (ACEO). The chip consists of three optimized tandem concentration processes for enhancing its performance. We confirmed that 50 nm nanoparticle solution was successfully extracted with the increased concentration of 6.2 times. This chip can also be applied for smaller nanoparticles. The developed concentrator chip would be beneficial for improving the detection limit of advanced sensing using nanoparticles.
