Monodisperse amino silica microspheres are widely used in chromatography for the separation and purification of biomolecules, such as proteins, peptides, and nucleic acids. Their uniform size and surface functionalization with amino groups enhance binding efficiency and resolution during separation processes. These microspheres are also employed in drug delivery systems, where their controlled size and surface properties allow for targeted and sustained release of therapeutic agents. In diagnostics, they serve as carriers for immobilizing enzymes, antibodies, or other biomolecules, improving the sensitivity and accuracy of assays. Additionally, they are utilized in catalysis as supports for immobilizing catalysts, enabling efficient and reusable catalytic processes. Their biocompatibility and tunable surface chemistry make them valuable in various biomedical and industrial applications.
