Carbosilane dendrimer and aggregatable carrier obtained using said dendrimer for drug delivery system

An aggregatable carrier material for drug delivery system comprising a compound shown in formula (I) and a protein and an aggregatable molecule having a targeted sequence presented part composed of:

• [Chemical formula 1]
• R1[(R2—Si)(—R3—Y)3]2 (I)
• wherein said targeted sequence presented part aggregates in an aqueous solvent to form a micelle having the diameter from 50 to 500 nm, and when said aggregatable molecule aggregates, said aggregated micelles emit fluorescence;
• wherein in the formula (I), R1 is silole group shown in the following formula (II);
• each of R2 and R3 is a hydrocarbon chain having 1 to 6 carbon atoms which may have the same or a different hydrocarbon chain or a ring;
• Y is the targeted sequence presented part bound via a halogen group or groups toward sulfur atom;
• and
• wherein X is silicon;
• R is phenyl group;
• and n is 4 in the formula (II).
