Abstract: Provided are phototherapeutic needle patches usable for phototherapy by using needle patches capable of injecting drugs or cosmetic substances to patients, and methods of manufacturing the same. A phototherapeutic needle patch may include a patch body attachable to skin of a patient, at least one microneedle protruding from the patch body, one end of the microneedle configured to deliver a drug through stratum corneum of the skin to inner tissues of the skin, and light grooves formed in a concave shape along a length direction of the microneedle in such a manner that therapeutic light radiated from a light source for phototherapy easily penetrates into the skin along the microneedle.

Abstract: Provided is a method of increasing corrosion resistance of a magnesium (Mg) member. The method includes preparing a Mg member, and ion-implanting a doping element into a surface of the Mg member. Herein, the doping element includes an element capable of increasing a Fermi energy level of magnesium oxide (MgO) when doped on MgO.
