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.

In drug delivery systems, these microspheres serve as carriers for controlled release of therapeutic agents. The amino groups on the surface allow for easy conjugation with drugs or targeting ligands, improving specificity and efficacy.

They are also utilized in diagnostic applications, particularly in immunoassays, where they act as solid supports for immobilizing antibodies or antigens. This enables sensitive and accurate detection of biomarkers in clinical samples.

Additionally, these microspheres find applications in catalysis, where their high surface area and functional groups facilitate the immobilization of catalysts, enhancing reaction efficiency and recyclability.

In environmental science, they are employed for the adsorption and removal of pollutants, such as heavy metals or organic contaminants, from water due to their high surface reactivity and stability.

Overall, their versatility makes them valuable in various scientific and industrial fields.
