    摘要： A continuous flow particle separation system for separating metallic and nonmetallic particles from a mixed-particle suspension includes a fluid channeling component defining an input channel and first and second output channels fluidly connected to the input channel at a bifurcated junction, a first electrode and a second electrode arranged proximate the input channel at least partially prior to the bifurcated junction, and an alternating current (AC) electric power source electrically connected to the first and second electrodes. The first and second electrodes have shapes configured to provide a spatially-gradient electric field across the input channel, and the AC electric power source is configured to provide an AC electric potential to the first and second electrodes to cause a separation of the metallic and nonmetallic particles by dielectrophoresis due to a difference in dielectrophoretic forces imposed on the metallic particles relative to those of the nonmetallic particles such that first output fluid flow in the first output channel has an enriched concentration of metallic particles and second output fluid flow in the second output channel has an enriched concentration of nonmetallic particles relative to the mixed-particle suspension in said input channel.

    摘要： Certain exemplary embodiments can provide a method, which can comprise isolating a single molecule of a solid organic compound via a microencapsulation process. The single molecule can be adapted for use in at least one of a drug, pharmaceutical application, microelectronic device, bioengineering application, biomedical product, agricultural product, or agricultural medicine. The microencapsulation process can comprise (1) adsorbing the single molecule on a template; and (2) dividing the template into species using electrostatic charge generating molecules.

    摘要： The procedure of dielectric electrophoresis (dielectrophoresis or DEP) utilizes field-polarized particles that move under the application of positive (attractive) and/or negative (repulsive) applied forces. This invention uses negative dielectric electrophoresis (negative dielectrophoresis or nDEP) within a microchannel separation apparatus to make particles move (detached) or remain stationary (attached). In an embodiment of the present invention, the nDEP force generated was strong enough to detach Ag-Ab (antigen-antibody) bonds, which are in the order of 400 pN (piconewtons) while maintaining the integrity of the system components.

    摘要： A separator of particulate material by the use of electric fields is comprised of a pair of spaced plates of a dielectric material between which particulate material is arranged to be fed, the material being propelled in a given direction by a vibratory feeder attached to the lowermost plate. A set of parallel spaced electrodes are provided on each of said plates out of contact with the material and extending in a direction laterally of said given direction, and an AC voltage is applied between the sets of electrodes so that alternating electrical fields are set up at spaced locations along said plates in said given direction. Certain of said particulate material is caused to be repelled by said electrical fields and deflected thereby to move in said direction laterally of said given direction while the remainder of said material moves generally in said given direction.
