Title:
SILICA SPHERE CONTAINING FLUORESCENT DYE MOLECULE
Document Type and Number:
WIPO Patent Application WO/2003/060037
Kind Code:
A1
Abstract:
Silica spheres containing fluorescent dye molecules. They are excellent not only in production stability but in performances. The silica spheres are prepared with fluorescent dye molecules represented by the following structural formula (1). R−CO−NH−(CH2)3−Si−(C2H5O)3 (1) In the formula, R represents a substance capable of having NHS in a side chain, e.g., FITC (fluorescein isothiocyanate).
