Publication number: 20230149567Abstract: 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.Type: ApplicationFiled: January 4, 2023Publication date: May 18, 2023Applicants: William Marsh Rice University, Durham UniversityInventors: James M. TOUR, Robert PAL, Victor GARCÍA LÓPEZ, Lizanne NILEWSKI

Patent number: 11351604Abstract: Methods for preparing a layered metal nanocomposite and a layered metal nanocomposite. The method includes mixing a magnesium salt and an aluminum salt to form a Mg2+/Al3+ solution. The Mg/Al has a molar ratio of between 0.5:1 to 6:1. Then a diamondoid compound is added to the Mg2+/Al3+ solution to form a reactant mixture. The diamondoid compound has at least one carboxylic acid moiety. The reactant mixture is heated at a reaction temperature for a reaction time to form a Mg/Al-diamondoid intercalated layered double hydroxide. The Mg/Al-diamondoid intercalated layered double hydroxide is thermally decomposed under a reducing atmosphere for a decomposition time at a decomposition temperature to form the layered metal nanocomposite.Type: GrantFiled: November 23, 2020Date of Patent: June 7, 2022Assignees: Saudi Arabian Oil Company, Durham UniversityInventors: Manohara Gudiyor Veerabhadrappa, Hugh Christopher Greenwell, Andrew Whiting, John Adrian Hall, Gasan Alabedi
