Abstract

Disclosed herein are a nanopreparation having a micelle structure for diagnosis or treatment of cancer diseases, and a method of preparing the same, and more particularly, a nanopreparation having a micelle structure available for diagonosis or treatment of cancer diseases and a method for preparing the same, wherein the nanopreparation is prepared by encapsulating a photosensitizer by forming micelle with polymeric lipid DSPE-mPEG. The nanopreparation having the micelle structure according to the present invention has a size of 12 nm or less by encapsulating hypericin, which is a photosensitizer, by forming micelle with polymeric lipid DSPE-mPEG having a molecular weight of 1500 to 2500. Resultingly, the nanopreparation easily overcomes a blood-tumor barrier (BTB) and an interstitial fluid pressure and has light induced cytotoxicity efficiency that is about more than 2.5 times higher than that of the case where hypericin is used alone.
