Title:
BLOCK COPOLYMER, BLOCK COPOLYMER-METAL COMPLEX COMPOSITE BODY, AND HOLLOW STRUCTURE CARRIER USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/058776
Kind Code:
A1
Abstract:
Disclosed is a hollow structure carrier which has extended release properties and selectively delivers not only a carcinostatic agent but also a water-soluble substance having a high molecular weight to a desired target tissue (especially to a tumor tissue). The hollow structure carrier is characterized by being obtained by association of block copolymer-metal complex composite bodies each of which contains a specific block copolymer and a metal complex.
