Abstract:
Provided are a dispersion comprising organic-inorganic hybrid type particles carried thereon with a biologically active substance, wherein the above particles can be obtained by allowing a block copolymer represented by Formula (I): PEG-block-poly(carbo) (I) (wherein PEG represents a polyethylene glycol segment, and carbo represents a repetitive unit having a carboxylate ion on a side chain) and an aqueous medium system capable of forming hydroxyapatite to coexist with the biologically active substance, and a preparing method for the same.
