Front Cover: Multiple consecutive recapture of rigid nanoparticles using a solid‐state nanopore sensor

DOI: 10.1002/elps.201700329 The cover picture shows a rigid particle recapture phenomenon using a solid‐state nanopore sensor. The application of two different colors, blue and red, represents two iterative translocation types, Cis to Trans and Trans to Cis. The sandglass shaped lines are indicating the electric field streamlines, and the seven spheres along the streamlines are showing a same particle at different points in time. The small and large transparent spheres represent the sensing zone and recapture zone respectively. The little blue and red dots are the representation of salt ions, K+ and Cl−.
