Title:
PARTICLES FOR SPECIMEN EXAMINATIONS
Document Type and Number:
WIPO Patent Application WO/2023/095865
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: particles that enables a high-sensitivity specimen examination employing a fluorescence depolarization method; and a method for producing the particles. Provided are particles each containing a particle matrix, in which the particle matrix comprises a polymer containing a styrene unit and an organosilane unit and a europium complex and is characterized in that a siloxane bond is contained in at least the surface of the particle matrix.
