  • Patent number: 11117804
    Abstract: Disclosed is a method of synthesizing graphene, wherein a Cu—Ni thin film laminate including a copper thin film and a nickel thin film formed thereon is placed in a chemical vapor depositor, brought into contact with a graphene precursor and subjected to chemical vapor deposition (CVD), thus synthesizing thickness-controlled graphene on the copper thin film, whereby the thickness of multilayer graphene can be easily and reproducibly controlled by adjusting only nickel thickness and CVD time, and a process window for obtaining reproducible results can be widened due to self-limiting properties whereby the maximum thickness of graphene is obtained after a certain synthesis time due to the thickness-controlled nickel thin film. Also, carbon atoms absorbed to the nickel thin film reach the copper thin film opposite thereto through internal diffusion of the metal laminate to thus grow graphene via surface-mediated reaction thereon, thereby improving the uniformity of synthesized graphene.

  • Patent number: 10973765
    Abstract: Disclosed are cell membrane-derived nanovesicles, a method of preparing the nanovesicles, and a pharmaceutical composition and a diagnostic kit using the nanovesicles. The cell membrane-derived nanovesicles may prevent potential adverse effects because intracellular materials (e.g., genetic materials and cytosolic proteins) unnecessary for delivering therapeutic or diagnostic substances are removed from the nanovesicles. In addition, as the nanovesicles may be targeted to specific cells or tissues, therapeutic or diagnostic substances may be predominantly delivered to the targeted cells or tissues, while delivery of the substances may be inhibited. Therefore, the nanovesicles may alleviate suffering and inconvenience of patients by reducing adverse effects of therapeutic substances and by improving efficacy of the substances.
