Dielectrophoresis (DEP) is a successful method to recover nanoparticles from different types of fluid. The DEP force acting on these particles is created by an electrode microarray that produces a nonuniform electric field. To apply DEP to a highly conducting biological fluid, a protective hydrogel coating over the metal electrodes is required to create a barrier between the electrode and the fluid...

The cover picture shows yellow and blue nanoparticles attracted to the electrodes of a microelectrode array designed for dielectrophoresis‐based particle collection in a high conducting media such as plasma. A protective hydrogel layer forms a dome structure over the electrodes when an electric field is applied. The domes likely have an insulative effect which intensifies...
