The overall goal of this experiment is to preconcentrate bioagents by confining the ion concentration polarization zone between two identical ion exchange membranes. This method can help answer key questions in the field such as how to detect low

The protocol for a novel ion concentration polarization (ICP) platform that can stop the propagation of the ICP zone, regardless of the operating conditions is described. This unique ability of the platform lies in the use of merging ion depletion and enrichment, which are two polarities of the ICP phenomenon.
