More particularly, the present invention relates to an active drug delivery system using magnetic particles. More specifically, when a polymer bead containing a core-shell structure drug and magnetic particles is prepared and an external magnetic field stimulus is applied to the polymer bead through magnet rotation, It was confirmed that the drug was released by vibrating and destroying the shell so that the drug delivery system based on the external stimulus-sensitive drug release system as the polymer beads containing the drug and the magnetic particles could quickly and accurately discharge the drug . |
