Title:
蛍光観察に使用する蛍光体集積ナノ粒子
Document Type and Number:
Japanese Patent JP6614161
Kind Code:
B2
Abstract:
The present invention provides 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 preferably 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 surface.
