Silica Microspheres

silica_16.jpg

Polysciences offers uniform, non-porous silica (SiO) microspheres available in nominal diameters of ~150 nm - 8 µm. These particles typically have size CVs of 10-15%.

Inorganic supports such as silica microspheres have become increasingly important for a variety of applications, including isolation of nucleic acids, cell separation, and immuno- and DNA-based assays.

Silica Microspheres

They offer the combined benefits of a broad platform and the unique properties of a silica substrate:

- Flexible silanization chemistries

- Unique refractive index and density

- Low autofluorescence

- Low nonspecific binding of many biomolecules

- Hydrophilicity

- Ease of handling
