Abstract: A microrobot of which a drug release is controlled by a sound wave applied from outside, and a method of manufacturing the microrobot are disclosed. The method includes mixing and storing magnetic nanoparticles and a drug in a biodegradable resist, and forming a microrobot having a three-dimensional (3D) porous structure at the resist through two-photon polymerization (TPP). The microrobot is formed to control a release rate of the drug stored in the resist by a sound wave applied from the outside.
