  • Patent number: 8039249
    Abstract: Disclosed is a disk based platform for separating and detecting cells that are labeled with immunomagnetic beads. A disk-like carrier board forms therein at least one flow channel structure, which includes an inner reservoir for receiving a sample fluid, an outer reservoir, and a plurality of micro flow channels arranged between and in fluid communication with the inner and outer reservoirs. When the disk-like carrier board spins, cells labeled with immunomagnetic beads are attracted by a magnetic attraction unit that is arranged above the disk-like carrier board and adjacent to the inner reservoir to thereby remain in the inner reservoir, and cells that are not so labeled are acted upon by a centrifugal force induced by the spinning of the disk-like carrier board to flow with the sample fluid from the inner reservoir through the micro flow channels into the outer reservoir.

  • Patent number: 8039250
    Abstract: Apparatus, system, and methods are provided for utilizing piezoelectric material for controlling a polymer through a nanopore. A reservoir is formed filled with conductive fluid. A membrane is formed that separates the reservoir. A nanopore is formed through the membrane. The membrane comprises electrical conductive layers, piezoelectric layers, and insulating layers. The piezoelectric layers are operative to control a size of the nanopore for clamping/releasing a polymer as well as to control the thickness of part of the membrane when a voltage is applied to the piezoelectric layers. Combinations of clamping/releasing the polymer and changing the thickness of part of the membrane can move a polymer through the nanopore at any electrically controlled speed and also stretch or break a polymer in the nanopore.

  • Patent number: 7955839
    Abstract: Systems and methods are provided for converting organic waste materials from a municipal waste stream to useful products. Organic waste materials having a wide range of compositions such as, for example, yard waste, food waste, paper, and the organic fraction of municipal solid waste are converted into a uniform biomass that is suitable for conversion to useful products, such as fuels. Through the use of a biomixer and a hydropulper, as well as through sorting and screening, the organic waste materials are progressively reduced in size and cleaned of contamination. The resulting uniform biomass is suitable for anaerobic digestion to produce biogas and a residual solid that is suitable for producing a high quality compost.

  • Patent number: 7943371
    Abstract: The present invention relates to joining two or more cartridges containing cell or tissue cultures from different organs found in the human body in fluid connection. It includes a vitro method and system for testing chemicals and agents as they pass through organs other than the brain or combinations of body systems including the brain. It greatly enhances the ability for researchers to test a proposed chemical or agent on human cells and tissue prior to testing it in vivo. Often, it is found that chemicals or agents have different reactions when tested on a single organ in vitro or in animals, than it does in the human body.
