  • Patent number: 9285338
    Abstract: Systems, devices, and methods are presented that facilitate electronic manipulation and detection of submicron particles. Time-multiplexed dielectrophoresis can be employed by cycling between two or more disparate electric fields during separate portions of a duty cycle. By cycling between these two or more disparate electric fields, two or more disparate particle types can be separated from one another based on differences in electrical properties of the two or more disparate particle types.

  • Publication number: 20140367260
    Abstract: An apparatus for identifying objects in a plurality of objects includes a portion which applies dielectrophoresis to the plurality of objects. The apparatus includes a portion which tracks the plurality of objects' reaction to the dielectrophoresis over time and extracts visible features about the plurality objects being tracked. The apparatus includes a portion which automatically identifies the objects from the plurality of objects based on the objects' reaction to the dielectrophoresis over time and the visible features of the objects. A method for identifying objects in a plurality of objects. A dielectrophoresis cartridge.

  • Patent number: 8815071
    Abstract: Systems, devices, and methods are presented that facilitate electronic manipulation and detection of submicron particles. A particle manipulation device contains a plurality of electrodes formed on an active semiconductor layer of an integrated circuit chip, where the electrodes and gap spacing between adjacent electrodes is submicron in size. The chip is oriented with its substrate face up, and at least a portion of the substrate is removed from the chip so the electrodes are in close proximity to a fluid chamber(s) placed over the chip, to facilitate manipulation of particles, contained in a buffer solution in the fluid chamber(s), to form a defined pattern. Innovative macro-scale optical detection is employed to detect the submicron particles, where a light beam is applied to the defined pattern, and interaction of the defined pattern with the light beam is detected and evaluated to facilitate detecting the particles.
