  • Patent number: 11147693
    Abstract: The present invention relates to an artificial foot including a foot body part, a toe part rotatably disposed at a first end of the foot body part, a toe joint connecting the foot body part and the toe part to each other, and an adapter disposed on a top of a second end of the foot body part. According to the artificial foot, since the toes of the artificial foot rotate when a wearer walks, when the artificial toes come in contact with the ground, energy is stored due to the load by the weight and the toes kick off the ground as much as the elastic energy accumulated by the spring, so the toe members of the artificial foot do not drag on the ground. Accordingly, the wearer does not need to lift up the hip joints, so the wearer can walk similar to normal walking.

  • Publication number: 20210308050
    Abstract: The present disclosure relates to a nanoparticle complex that is taken into cells to be used for the treatment of diseases, and a method of manufacturing the same using a top-down process. In the top-down process, surfaces of nanoparticles are modified with a lipid-based material having high stability and excellent biocompatibility, thereby improving endocytosis efficiency. A lipid structure having a tube shape is bonded to a portion of the surface of the nanoparticle, so that the nanoparticle complex undergoes endocytosis, directly penetrates a cell membrane, and is effectively taken into spheroid-type tumor cells. The lipid structure is not directly attached to the nanoparticles, lipid-based lipidomes (such as bubbles and liposomes) are bonded to the nanoparticles, and mechanical force is applied thereto to thus crush the lipidomes, so that the lipid structure is formed on the surface of the nanoparticle.
