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 chromatographic processes. These microspheres are also employed in drug delivery systems, where their surface amino groups allow for the conjugation of therapeutic agents, enabling targeted and controlled release. In diagnostics, they serve as carriers for immobilizing enzymes, antibodies, or other biomolecules, improving the sensitivity and specificity of assays. Additionally, they are utilized in catalysis, where the amino groups act as active sites or support for catalytic materials, enhancing reaction efficiency. Their biocompatibility and tunable surface properties make them valuable in biomedical research, particularly in cell separation, tissue engineering, and biosensing applications.
