Beschreibung
Zusammenfassung:	Devices, systems, and methods for applying a dielectrophoretic force on a particle include: a cell defining at least one channel for confining the particle; and a first electrode and a second electrode electrically isolated from the first electrode, at least one of the first and second electrodes being formed from a two-dimensional (2D) material providing an atomically sharp edge. The first and second electrodes are arranged sufficiently close to one another and sufficiently close to the channel such that application of a sufficient voltage across the first and second electrodes generates an electric field in at least part of the channel, the electric field having an electric field gradient sufficient to apply the dielectrophoretic force on the particle in the channel.
