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 make them ideal for high-resolution separations in HPLC and affinity chromatography.

In drug delivery systems, these microspheres serve as carriers for controlled release of pharmaceuticals, leveraging their biocompatibility and ability to be surface-modified for targeted delivery. They are also employed in diagnostic applications, where they act as solid supports for immobilizing antibodies, enzymes, or other biomolecules in immunoassays and biosensors.

Additionally, these microspheres are utilized in catalysis, where their amino groups can anchor metal nanoparticles or other catalytic species, enhancing reaction efficiency and selectivity. In material science, they are incorporated into composites to improve mechanical properties or used as templates for synthesizing advanced nanostructures.

Furthermore, they find applications in environmental remediation, such as the removal of water contaminants and adsorption of heavy metals, due to the binding affinity of their amino groups.

Their versatility and functional properties make them valuable across diverse scientific and industrial fields.
