Provided is a method of synthesizing apatite powder by emitting a laser beam to a surface of a substrate immersed in a precursor solution. The method is including immersing a substrate in an apatite-forming precursor solution, emitting a laser beam to a region on a surface of the substrate immersed in the precursor solution, and obtaining apatite powder generated in the precursor solution.

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.

Phototherapeutic needle patches and methods of manufacturing the same

Provided is an implant having a controlled generation rate of reactive oxygen species and a method of controlling generation of reactive oxygen species using the same. The implant having a controlled generation rate of reactive oxygen species according to the present invention includes a body formed of a metallic material and having a groove, a first filling metal filling one region of the groove, and a second filling metal filling the groove on the first filling metal, wherein the second filling metal has an ionization tendency different from that of the first filling metal.
