文摘

In nanofluidic resistive pulse sensing (RPS) platforms, particles pass through a nanopore by an external electric field. If particles pass through the immiscible liquid-liquid interface formed inside a pore, the effective volume is increased with conformal coating and the translocation speed is decreased by the interfacial tension of the interface. Therefore, both the resistive pulse signal and the translocation time of nanofluidic RPS platforms can be enhanced simultaneously, as presented by W. Choi, R. Kwak, and co-workers in article number 1601725.
