In this paper, a combination of vacuum and centrifugal forces was studied for recirculate samples inside the chambers. Detection low concentration samples, rare molecules such as cancer cells or certain proteins among large volume of samples is still challenging in microfluidic based ELISA (enzyme-linked immnosorbent assay). In order to achieve high success rate of detection, recirculating of samples in assay chambers is one of the useful approaches. In this study, vacuum-driven microfluidic was used with the combination of the centrifugal force to achieve recirculating samples inside the chamber.
