摘要:
The present invention provides a drug delivery material, which is a conjugate of 1) a drug-carrying molecular assembly, 2) a linker and 3) a substance that recognizes activated platelet, injury site of blood vessel and/or inflammatory tissue, and capable of efficiently delivering a drug to a desired site, during which the drug under delivery does not affect sites other than a desired site (hence, low possibility of causing side effects), which releases the drug only at the desired site without requiring an external means and allows the drug to exhibit an effect.
