  • Patent number: 11285494
    Abstract: A centrifuge rotor having a curved shape is offset on a spinning rotor base and creates contiguous areas of low to high centrifugal force depending on the distances from the axis of the rotor base and a method of separating components in a fluid based upon a difference in density of the components, the method comprising the steps of providing to a rotor as described herein the fluid containing the mixed together components to be separated based upon the difference in density of the mixed together components; continuously flowing the components in the fluid to the rotor through an input tube connected to the input port while the rotor is spinning about a centrifugal axis of rotation; separating the components in the fluid into fractions based upon the difference in density of the mixed together components with the use of centrifugal force when the rotor is spinning; collecting components having i) a first density via a first tube connected to the output port at the first end on the rotor, ii) a second density

  • Patent number: 10751464
    Abstract: Method and apparatus for removing high density particles from a biological fluid such as blood using aphaeresis. The particles are preferably sub-micron in size and denser than normally occurring components of the fluid and can be removed by a modified reverse-flow gradient density centrifuge without damaging the fluid. The particles can be provided to a patient in vivo or added to the fluid after it is removed from the patient. Some particles can carry and deliver oxygen and scavenge carbon dioxide. Other particles are conjugated to capture molecules for attaching to targets such as cancer cells, viruses, pathogens, toxins, or excess concentrations of a drug or element in the fluid. The targets are then removed from the fluid along with the particles by the aphaeresis instrument.

  • Patent number: 9956180
    Abstract: A method and apparatus for continuous removal of sub-micron sized particles and other materials attached thereto such as cancer cells and bacteria from blood and other liquids. A centrifuge rotor having a curved shape is offset on a spinning rotor base and creates contiguous areas of low to high centrifugal force depending on the distances from the axis of the rotor base. This creates a density gradient field that separates materials of different densities input to the centrifuge that exit via different outputs. A monitor detects components of the fluid that are mixed with the particles before they exit the centrifuge. If there are any unwanted components detected with the particles logic circuitry changes the speed of rotation of the rotor, and the flow rate of pumps inputting and removing separated fluid and particles to and from the centrifuge until there are no unwanted components in the fluid exiting with the particles from the centrifuge.

  • Patent number: 9938396
    Abstract: A concept and synthesis technology for a composite nanoparticle material which can be used to develop nanocomposite films and suspension with 1) dynamic refractive index control across a wide temperature and wavelength of light, and specified refractive index range, or 2) magnetic susceptibility or electronic conductivity over a wide temperature, magnetic field and electric field range. Core-shell nanoparticles can be made from two or more materials whose temperature dependent, electric field dependent or magnetic field dependent properties compensate one another will dynamically maintain a targeted refractive index, electronic conductivity or magnetic susceptibility over a specified temperature, electric and/or magnetic field range. Mixtures of composite nanoparticles with complementary behavior can optionally be used to widen the operational range of the nanocomposite material further or dampen temperature dependency in a controlled manner, e.g.

  • Publication number: 20160258869
    Abstract: A nano-pH sensor can include a nanoparticle having an outer surface functionalized by a carboxy functional group. The nanoparticle is reversibly aggregated as a function of pH and is generally non-toxic. A fluorometer can be oriented to expose the nanoparticles to a light source at a given wavelength. Further, the fluorometer can be configured to detect changes in fluorescence of the gold nanoparticle with changes in pH.

  • Patent number: 9415021
    Abstract: An artificial oxygen carrier (AOC) for use as a blood substitute in the body. A first gas permeable shell encloses an oxygen carrying agent. The first gas-permeable shell has a second oxygen carrying agent surrounding it, and there is a second gas-permeable shell enclosing the second agent. The concentric shells are not subject to turbulent breakup, or chemical decomposition, and do not release the oxygen carrying agents into the blood.
