Monodisperse carboxy silica microspheres are widely used in biomedical research and diagnostics due to their uniform size and surface functionality. These microspheres serve as excellent carriers for drug delivery systems, enabling controlled release and targeted therapy. Their carboxyl groups allow for easy conjugation with biomolecules, such as antibodies, peptides, or DNA, making them valuable in immunoassays, biosensors, and molecular diagnostics.

In chromatography, they are employed as stationary phases for high-resolution separation of proteins, nucleic acids, and other biomolecules. Their consistent size and surface properties ensure reproducibility and efficiency in analytical applications. Additionally, they are utilized in cell sorting and imaging techniques, where their uniform characteristics enhance accuracy and reliability.

These microspheres also find applications in material science, acting as building blocks for creating structured materials with precise properties. Their functionalized surface facilitates the development of advanced composites, coatings, and catalysts. Overall, their versatility and tunable properties make them indispensable in various scientific and industrial fields.
