Used as a surface modifier in drug delivery systems to enhance cellular uptake and targeting efficiency. Its amine-functionalized surface allows for covalent attachment of biomolecules such as antibodies, peptides, or fluorescent dyes, making it valuable in diagnostic and imaging applications. Commonly employed in biosensors due to its ability to immobilize enzymes or DNA probes while maintaining their activity. Applied in chromatography as a stationary phase for the separation of biomolecules and organic compounds. Also utilized in catalysis support where the amine groups act as anchoring sites for metal catalysts. Effective in environmental applications for adsorption of heavy metals and anionic pollutants from water due to its positive surface charge at low pH. Frequently used in nanocomposite materials to improve dispersion and interfacial bonding in polymer matrices.
