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 organic/inorganic hybrid-porous biodegradable polymer scaffold, which includes basic ceramic nanoparticles, an animal tissue or cell-derived bioactive first extracellular matrix material, and a biodegradable polymer and in which inner walls of pores are coated with a second extracellular matrix material.

Organic/inorganic hybrid-biodegradable porous polymer scaffolds and preparation method thereof

A biomedical implant according to this invention comprises ceramic complex, which includes a surface-modified basic ceramic particles, which are basic ceramic particles modified their surface with first biodegradable polymers, and the second biodegradable polymers. The first and second biodegradable polymer are combined each other and form a stereo complex. The biomedical implant has a superior effect to suppress inflammation caused by degradation of biodegradable polymers with improving its mechanical property.
