Abstract: The present disclosure relates to a temperature-sensitive nanoparticle/hydrogel complex, and more particularly, the temperature-sensitive nanoparticle/hydrogel complex for sustained-release drug release that can delay the drug release rate at the administration site, thereby maximizing the drug treatment efficacy at the local site by the interaction between the drug and the nanoparticles as well as the interaction between the drug and the hydrogel when mixing a drug-free nanoparticle/hydrogel complex and a predetermined drug.

Abstract: The present invention relates to a bending adjustment apparatus using a curved bar, a bendable electronic device including the same, and a method for adjusting bending of the electronic device. The bending adjustment apparatus according to the present invention includes: a guide unit attached to a flat panel member made of a flexible material; at least one curved bar extending in a curved shape and rotatably installed in the guide unit; and a power transmission drive unit configured to rotate the curved bar so as to adjust a tensile force applied to the flat panel member corresponding to a curved shape of the curved bar. Accordingly, the degree of bending of the panel may be controlled by adjusting an angle formed by the curved direction of the curved bar with the panel in a state in which the bent-type curved bar is coupled to the flat panel member such as a display panel, and the curvature of the panel may be adjusted to a desired degree by controlling the rotation of the curved bar to an arbitrary angle.

Abstract: A method for preparing a nanoparticle/hydrogel composite for a drug carrier according to one embodiment of the present invention comprises the steps of: forming stabilized lipid-based nanoparticles by irradiating an ultrasonic wave on a mixture of phosphatidylcholine and polysorbate 80 and then mixing a first polymer and freeze-drying same; and forming a lipid-based nanoparticle/hydrogel composite by mixing a second polymer and hyaluronic acid with the lipid-based nanoparticles and freeze-drying same.
