  • Patent number: 11154623
    Abstract: Embodiments of the present disclosure pertain to methods of opening a lipid bilayer by associating the lipid bilayer with a molecule that includes a moving component capable of moving (e.g., rotating) in response to an external stimulus; and exposing the molecule to an external stimulus before, during or after associating the molecule with the lipid bilayer. The exposing causes the moving component of the molecule to move and thereby open the lipid bilayer (e.g., by pore formation). The external stimuli may include an energy source, such as ultraviolet light. The opened lipid bilayer may be a component of cell membranes in vitro or in vivo. The opening of the lipid bilayer may allow for the passage of various materials (e.g., active agents, such as peptide-based drugs) through the lipid bilayer and into cells. Additional embodiments of the present disclosure pertain to the aforementioned molecules for opening lipid bilayers.

  • Publication number: 20210257679
    Abstract: Systems and methods that utilize a separator coated by particles for Li dendrite detection in an ordinary two-electrode battery system. The particles can be red phosphorus (RP) particles and/or other particles that are poor electronic conductors, are able to react with Li, and will form an insoluble product with Li, such as silicon, germanium, arsenic, metal oxides, metal halides, metal chalcogenides, chalcogenides, and LiMxEyOz (M=metal, E=nonmetal, O=oxygen, x?0, y?0, z?0). These other particles can be used by themselves or in combination with one another. No additional electrode is needed, and the presence of Li dendrites can be detected simply based on the voltage profile during the charging step.

  • Publication number: 20200222453
    Abstract: Modified hydrophilic carbon clusters (HCCs), poly(ethylene glycol)-hydrophilic carbon clusters (PEG-HCCs) and similarly structured materials like graphene quantum dots (GQDs), PEGylated GQDs, small molecule antioxidants, and PEGylated small molecule antioxidants. These materials have been modified with an iron chelating moiety, deferoxamine, or a similar chelating moiety. By exploiting common binding sites, the carbon nanostructure facilitates intracellular transport including in mitochondria, reduces oxidative breakdown of the chelator moiety prior to treatment, and reduces both the cause and consequences of metal induced oxidative stress within the body thus providing a novel form of therapy for a range of oxidative and metal-related toxicities. Graphenic materials can be used for the treatment of acute and chronic mitochondrial electron transport chain dysfunction.

    Abstract: Methods that expand the properties of laser-induced graphene (LIG) and the resulting LIG having the expanded properties. Methods of fabricating laser-induced graphene from materials, which range from natural, renewable precursors (such as cloth or paper) to high performance polymers (like Kevlar). With multiple lasing, however, highly conductive PEI-based LIG could be obtained using both multiple pass and defocus methods. The resulting laser-induced graphene can be used, inter alia, in electronic devices, as antifouling surfaces, in water treatment technology, in membranes, and in electronics on paper and food Such methods include fabrication of LIG in controlled atmospheres, such that, for example, superhydrophobic and superhydrophilic LIG surfaces can be obtained.
