Devices and methods for performing dielectrophoresis are described. The devices contain sample channel which is separated by physical barriers from electrode channels which receive electrodes. The devices and methods may be used for the separation and analysis of particles in solution, including the separation and isolation of cells of a specific type. As the electrodes do not make contact with the sample, electrode fouling is avoided and sample integrity is better maintained.

A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

A nanocarbon separation method includes: a step of preparing a plurality of liquids with different specific gravities in which at least one of the plurality of liquids is a dispersion liquid in which a mixture of nanocarbons with different properties is dispersed; a step of sequentially injecting the plurality of liquids into an electrophoresis tank so that the specific gravities of the liquids decrease from a bottom to a top of the liquids in a direction of gravitational force; and a step of separating the mixture of the nanocarbons by moving a part of the mixture toward an electrode side disposed in an upper part of the electrophoresis tank and moving a remainder of the mixture toward an electrode side disposed in a lower part of the electrophoresis tank by applying a direct current voltage to the electrodes.

This development corresponds to a system with electronic components for the treatment of high-concentration fluids or solutions or suspensions with solutes, such as wastewater treatment, obtaining valuable elements that are part of a fluid, seawater desalination, among other processes. The system comprises electrodes, tank, solid-state electronic device, a system management algorithm, and an optional solids removal device. This development also intends to protect a fluid or solution treatment procedure that generally involves two joint or sequential stages, whereby a dynamic electro-coagulation takes places first, followed by dynamic electro-flocculation, in order to separate liquids from dissolved solids or solutes from a solution.
