Abstract:
The present invention provides a molecular assembly which is less likely to accumulate in tissue other than cancer tissue, is highly safe for a living body, and can be prepared by a simple and safe method and whose particle size can be easily controlled. The present invention provides a molecular imaging system and a molecular probe useful for the system, and a drug delivery system and a molecular probe useful for the system. The present invention provides a method for preparing molecular assembly, by which the particle size of molecular assembly having a signal group or a drug can be arbitrarily controlled in order to allow the molecular assembly to effectively accumulate in cancer tissue by utilizing EPR effect. A molecular assembly comprising: an amphiphilic block polymer A comprising a hydrophilic block chain and a hydrophobic block chain having 10 or more lactic acid units; a hydrophobic polymer A2 having at least 10 or more lactic acid units; and/or a labeled polymer B comprising at least 10 or more lactic acid units and a labeling group.

Claim (Index 2):
The method for preparing the molecular assembly according to  claim 1 , wherein the hydrophobic polymer A2 is selected from the group consisting of:\n a hydrophobic polymer whose 10 or more lactic acid units are composed of L-lactic acid units; a hydrophobic polymer whose 10 or more lactic acid units are composed of D-lactic acid units; and a hydrophobic polymer whose 10 or more lactic acid units are composed of L-lactic acid units and D-lactic acid units.
