Abstract: A microneedle patch includes a substrate and a plurality of microneedles disposed on the substrate, each of the plurality of microneedles including: (i) one or more polymers dissolvable in human skin layer, (ii) a plurality of lipid nanoparticles, and (iii) a nucleic acid drug encapsulated by the plurality of lipid nanoparticles; each of the plurality of microneedles being defined with a tip end portion that enables dermal penetration, and the microneedle patch being adapted to be stored at room temperature.

Abstract: The invention discloses a motor (501) and a hair dryer having the same, the motor (501) comprises a rotor assembly (16) and a stator assembly (15), wherein the motor (501) also comprises a bracket (17) for supporting the rotor assembly (16) and the stator assembly (15), and the rotor assembly (16) is connected with a fan blade (502); the bracket (17) comprises a first cylinder (8) for supporting the rotor assembly (16) and a second cylinder (9) for protecting the fan blade (502); the first cylinder (8) is connected with the second cylinder (9), and at least a part of the first cylinder (8) is located outside the second cylinder (9). By integrating the fan blade (502) and the motor (501) as a component, the assembly steps of the whole machine are simplified and the difficulty of assembly is reduced. The user experience is good by using the hair dryer with the motor.
