  • Patent number: 9873126
    Abstract: Embodiments of the present disclosure provide for devices, methods for separating particles, and the like.
    Type: Grant
    Filed: October 11, 2016
    Date of Patent: January 23, 2018
    Assignee: University of Georgia Research Foundation, Inc.
    Inventors: Leidong Mao, Taotao Zhu, Mark A. Eiteman
  • Publication number: 20170319443
    Abstract: The present invention generally relates to microfluidic droplets and, in particular, to multiple emulsion microfluidic droplets. In one set of embodiments, multiple emulsion droplets are provided, where an inner shell of the droplet is relatively thin, compared to the outer shell (or other shells) of the droplet. For instance, in one set of embodiments, the inner droplet has an average thickness of less than about 1000 nm. In some cases, the inner shell may be rigidified, e.g., to form a gel or a polymeric layer. This may be useful, for example, for preventing coalescence of fluids within the microfluidic droplet. Other embodiments of the present invention are generally directed to methods of making such droplets, methods of using such droplets, microfluidic devices for making such droplets, and the like.

  • Publication number: 20170296996
    Abstract: The present invention generally relates to microparticles and, in particular, to systems and methods for encapsulation within microparticles. In one aspect, the present invention is generally directed to microparticles containing entities therein, where the entities contain an agent that can be released from the microparticles, e.g., via diffusion. In some cases, the agent may be released from the microparticles without disruption of the microparticles. The entities may be, for instance, polymeric particles, hydrogel particles, droplets of fluid, etc. The entities may be contained within a fluid that is, in turn, encapsulated within the microparticle. The agent may be released from the entity into the fluid, and then from the fluid through the microparticle. In such fashion, the release of agent from the microparticle may be controlled, e.g., over relatively long time scales.

  • Publication number: 20160374918
    Abstract: A stable cosmetic agent that includes an encapsulated particle in a core-shell configuration. The encapsulated particle is formed by coating nicotinamide riboside powder or a nicotinamide riboside containing material with one or more encapsulating agents. The stable encapsulated nicotinamide riboside particles exhibit less than 20% hydrolysis when incorporated into an aqueous skin care composition.

  • Patent number: 9517474
    Abstract: Embodiments of the present disclosure provide for devices, methods for separating particles, and the like. In general, embodiments of the present disclosure include non-uniform magnetic field-assisted processes and devices for the separation of particles (e.g., cells) within a magnetic fluid. Under non-uniform magnetic fields, particles such as cells can experience the generated magnetic field direction to produce a magnetic buoyancy force, analogous to buoyancy force, as magnitude of the force is proportional to the volume of cell. This force can be used to spatially separate cells of different sizes. In some embodiments, devices for separating particles are provided having a magnetic device configured to direct a non-uniform magnetic force onto the magnetic fluid and the particles; and a plurality of outlets, wherein the non-uniform magnetic force causes the types of particles to be separated and flow into different outlets.
