Abstract
A core-shell particle including a signal-generating substance therein, wherein the core-shell particle consists of (1) a core portion substantially made of a water-insoluble polymer compound; and (2) a shell portion substantially made of a water-soluble polymer compound having a reactive functional group, and covering a surface of the core portion in the manner of bristles of a brush; and the core portion and the shell portion are, as a whole, a block copolymer of a water-insoluble polymer and a water-soluble polymer, characterized in that the signal-generating substance is included in the core portion, is disclosed, and a process for producing the same is also disclosed. The core-shell particle including a signal-generating substance therein is useful as a labeling substance in which neither radioisotopes having handling restrictions nor unstable enzymes are required, a high sensitivity superior to fluorescent substances is achieved, and nonspecific absorption does not occur.
