Disclosed are a coating agent for drug releasing stents, a method for preparing the same and a drug releasing stent coated therewith. The coating agent for drug releasing stents comprises nanoparticles with a biologically active material entrapped therein, wherein the particles are formed of a polyethyleneimine(PEI)-deoxycholic acid(DOCA) polymer (PDo) in which 1 ~ 8 moles of DOCA are grafted per mole of PEI. |
