CD Bioparticles provides silica particles with a high amount of covalently bound fluorescence dye in the silica matrix. The fluorescent silica particles we offer consist of ultra-monodisperse spherical silica particles loaded with a fluorescent dye, providing fluorescence capabilities comparable to heavy metal quantum dots (which are generally classified as toxic), with excitation/emission values dependent on the dye/color. Dye-doped silica particles allow different dyes and drugs to be accommodated in the silica matrix while still allowing control over the resulting particle size and shape. Furthermore, their adaptable and well-understood chemistry allows simple and straightforward modifications of particle surface chemistry, providing reactive sites for further functionalization.

Currently, fluorescent silica particles have been widely used in biology and biomedicine as a potential fluorescent probe. Various biomedically important targets, such as cancer cells, bacteria, and individual biomolecules, could be labeled with highly fluorescent silica particles. With excellent fluorescence properties, silica particles with various fluorescence and functional groups we provide can be used in many fields, such as biomarkers, biological imaging, and biosensing.

The fluorescent silica nanoparticles are available with red fluorescence (excitation: 569 nm, emission: 585 nm), green fluorescence (excitation: 485 nm, emission: 510 nm) and blue fluorescence (excitation: 354 nm, emission: 450 nm). Different surface functionalities including Si-OH, NH2 and COOH enable covalent binding of proteins, antibodies, oligonucleotides, and other molecules.
