  • Publication number: 20250073138
    Abstract: The present invention relates to a lipid-based nanoparticle composition for enhancing transdermal absorption and a method of preparing the same. The present invention provides a carrier for enhancing transdermal absorption that enhances or promotes chemical bonding with skin tissue by modifying the surface of lipid nanoparticles with a polyphenol. This may demonstrate the synergistic effect of active and passive transdermal delivery systems.

  • Publication number: 20250057767
    Abstract: The present invention relates to hybrid exosomes, a use of the same, and a preparation method of the same, and the hybrid exosomes provided from the present invention have excellent skin inflammation amelioration, skin wrinkle amelioration, skin moisturization efficacy, and skin regeneration efficacy compared to using hydrangea-derived exosomes and liposomes alone, and thus can be effectively utilized as a cosmetic composition containing the same as an active ingredient. In addition, the hybrid exosomes have better stability and biocompatibility compared to existing exosomes.

  • Publication number: 20190188345
    Abstract: The present invention provides a method for diagnosing a rotation device by means of a rotor-bearing-foundation model, the method characterized by utilizing the characteristics of a simulation rotor system. To this end, the present invention comprises the steps of: simulating a rotation device as a rotor system; forming a mathematical model for the rotor system; estimating the state of the rotation device by means of the mathematical model and a vibration measurement value of the rotation device; and diagnosing for abnormalities in the rotation device from the changes in an estimated value. Therefore, since a rotation device is diagnosed for abnormalities by means of forming a mathematical model for a rotor system, the present invention enables more accurate diagnosis of the rotation device.
