  • Publication number: 20200289425
    Abstract: Disclosed herein are drug-containing vesicles, each of which includes a carbon dot liposome (C-dot liposome) formed by a plurality of Janus particles, which are self-assembled into the C-dot liposome; and a drug encapsulated within the C-dot liposome. Also disclosed herein is a method of producing the drug-containing vesicles. The method includes, mixing a plurality of Janus particles with a drug solution (e.g., an anti-cancer drug solution) to form a mixed solution; and producing the drug-containing vesicles either by a film-hydration method or an injection method. In the film-hydration method, the mixed solution is condensed until a film-like structure is formed; and sonicating the film-like structure in a salt solution to produce the drug-containing vesicle. In the injection method, the mixed solution is rapidly injected into a salt solution to produce the drug-containing vesicle. Also encompasses in the present disclosure are methods for treating a subject afflicted with a cancer.

  • Patent number: 9620087
    Abstract: A multimedia interaction system includes: multiple electronic devices and a location detection circuit. The location detection circuit dynamically detects respective electronic device's spatial position and orientation. When an user instructs a source electronic device of the multiple electronic devices to transmit a target image object toward a selected direction, the source electronic device decides a target direction according to a location of a first candidate electronic device and the selected direction if a relative position between the first candidate electronic and the selected direction satisfies a first predetermined condition. The source electronic device transmits a target command corresponding to the target image object to a second candidate electronic device to perform corresponding multimedia interaction operations only if a relative position between the second candidate electronic and the target direction satisfies a second predetermined condition.
