The identity of the dye is proprietary; however, it has similar properties to Atto dye. The dye is covalently linked inside the silica matrix. The "ultrastable" particles are doped with a more stable and brighter dye compared to the "normal" beads.

Application
The use of labeling or staining agents has greatly assisted the study of complex biological interactions in biology and the fluorescent labeling of biomolecules has been demonstrated as an indispensable tool in many biological studies. By virtue of excellent fluorescence properties the Silica nanobeads find application in biological labeling, bioimaging, biosensing etc. Ultrastable particles exhibit a very high resistance to photobleaching and can be used in single-particle imaging as well as in super resolution techniques such as stimulated emission depletion (STED) microscopy.
