Abstract
The present invention may provide phosphor-integrated nanoparticles whose precipitation and/or aggregation, particularly aggregation can be inhibited upon carrying out immunostaining therewith and which can thus be used for staining even after long-term storage without requiring a complicated operation, the phosphor-integrated nanoparticles preferrably maintaining excellent performance, such as staining properties, even after long-term storage. The phosphor-integrated nanoparticles of the present invention have an average sphericity (f) of 0.80 to 0.95 and preferably have an average circumference ratio (R) of 0.50 to 0.95. More preferably, the matrix of the particles contains an organic compound, the phosphor-integrated nanoparticles have an average particle size of 300 nm or less, and a biological component-binding molecule is bound on the particle
