  • Publication number: 20230245410
    Abstract: Disclosed herein is a method for providing guided instructions or support using a virtual object. The method comprises at a first computing device in communication with one or more input devices and a second computing device, capturing, using the one or more input devices, one or more images, determining an identity of an object using the one or more images, and transmitting the identity of the object to the second computing device. The method further comprises receiving from the second computing device an indication of a first input received at the second computing device and presenting a first view of the object comprising a first annotation that corresponds to the first input received at the second computing device.

  • Patent number: 9517277
    Abstract: Provides is a therapeutic technology that combines the phototoxic and immune-stimulating ability of photodynamic therapy with the widespread effectiveness of the immune system to reduce the viability of such as cancer cells and tumors. The nanoparticle compositions of the disclosure combine an immunostimulant with a photosensitizer using a nanoparticle delivery platform. For example, zinc pthalocyanine, which is a long-wavelength absorbing photosensitizer, integrated into a polymeric nanoparticle core made up of poly(D,L-lactic-co-glycolic acid)-b-poly(ethylene glycol) (PLGA-b-PEG). The outside surface of the core can be coated with metallic nanoparticles, which are then modified with CpG-ODN. Metastatic mouse breast carcinoma cells showed significant photocytotoxicity of the hybrid after irradiation with a 660 nm LASER light and this activity was remarkably better than either treatment alone.
