Inorganic supports, such as silica microspheres, have become increasingly important for a variety of applications. They offer the combined benefits of working with a bead platform and the unique properties of a silica substrate, including: flexibility, large specific surface area, improved binding kinetics over planar surfaces, robust statistics, flexible silanization chemistries, unique refractive index and density, low autofluorescence, low nonspecific binding of many biomolecules, hydrophilicity, and easy manipulation.

Bangs offers a range of silica bead sizes (from ~0.15µm-5µm) to meet the requirements of a variety of applications.
