Abstract

We present an experimental study of a novel method and device enabling 1000-fold acceleration of surface-based reactions. Our method leverages isotachophoresis (ITP) to deliver a highly focused sample to a pre-functionalized surface, thus enabling rapid reaction at the sensor site. Using electric current readings alone, we are able to precisely detect the location of the focused sample and deliver it with an accuracy of 50 μm to the sensor site. The presented assay is a one-step react-and-wash assay which can be performed in a simple channel and does not require flow control elements or moving parts.
