Abstract
The present invention relates to microparticles that can be used as drug-loaded hydrogel particles for embolization and a method for manufacturing same. The microparticles of the present invention have a very excellent anticancer agent adsorption ability, a short anticancer agent adsorption time, and a controllable decomposition time when administered in vivo. Therefore, when the microparticles of the present invention are used in chemoembolization, not only the anticancer effect is excellent, but also side effects can be minimized.
