Abstract: An implantable microneedle and a manufacturing method therefor is disclosed. The implantable microneedle includes a coating layer for covering at least one part of the surface of a tip part of the microneedle. When exposed to moisture, the coating layer can be separated from the tip part of the microneedle and thus be implanted.

An implantable microneedle according to the present invention comprises a coating layer for covering at least one part of the surface of a tip part of the microneedle. When exposed to moisture, the coating layer can be separated from the tip part of the microneedle and thus be implanted.

Abstract: An implantable substance delivery vehicle of the present invention comprises: a pin comprising a bevel tip and an engraved groove on the surface of the bevel tip; and a substance to be delivered into the body, inserted so as so as to protrude outwardly from the tip, wherein, when the implantable substance delivery vehicle is used for implantation, the substance to be delivered into the body, inserted so as so as to protrude, is caught in tissue so as to be readily detached.

Abstract: A photocrosslinkable hydrogel may comprise a radioisotope-labeled photocrosslinkable compound or a pharmaceutically acceptable salt thereof, which may be used as a composition for radiotherapy, a composition for radiodiagnostic imaging and a composition for anticancer treatment. The hydrogel is excellent in staying in a local area requiring radiation treatment, so that it can be treated while minimizing damage to surrounding tissues. In addition, it can be used in combination with an anticancer agent and used as a pharmaceutical composition for anticancer treatment, so that cancer can be effectively treated. The hydrogel can be manufactured on site immediately and conveniently using a portable microfluidic system, thereby maximizing the radiation treatment effect.
