A passive microfluidic device is reported for continuous microparticle enrichment. The microparticle is enriched based on the inertial effect in a microchannel with contracting‐expanding structures on one side where microparticles/cells are subjected to the inertial lift force and the momentum‐change‐induced inertial force induced by highly curved streamlines....

The continuity equations, which describe the movement of ions in liquid solutions under the influence of an external stationary electric field, as it is utilized in electrophoresis, were introduced a long time ago starting with Kohlrausch in 1897. From that time on, there have been many attempts to solve the equations and to discuss the results. In...

Segregation of phases in the vicinity of hydrophobic surfaces may turn out to be immensely consequential towards altering the coupling of electrostatics and hydrodynamics over interfacial scales. Here, we review the fundamental advances towards bringing out the various facets of electrokinetic transport over hydrophobic interfaces. We lay significant...

Aflatoxin contamination in agricultural products poses a great threat to humans and livestock. The aim of this study was to establish a simple, rapid, highly sensitive, and inexpensive method for the simultaneous detection of aflatoxin B1, B2, G1, and G2 in agricultural products. We used a vortex assisted low density solvent–microextraction (VALDS‐ME)...

DOI: 10.1002/elps.201800266 The cover picture shows inorganic salts (represented by NaCl crystal) and amino acids, important biosignatures in the search for extraterrestrial life. As in Earth's oceans, samples from Ocean Worlds such as Europa (Jupiter's moon) and Enceladus (Saturn's moon) are expected to contain high amounts of salts. We have developed...
