Anwendung
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.[1][2]

Are they stable in high ionic strength buffers?
1 answer-
These nanobeads are negatively charged in water. Alkaline solutions, such as ammonia, may improve stability. The stability in a high ionic strength buffer would depend on the specific components, but most often would not enhance the stability.
