Carboxylated iron oxide nanoparticles provide optimized surface functionalization, superior biocompatibility, and enhanced dispersion stability. Designed for advanced biomedical and industrial applications, they ensure efficient conjugation, extended durability, and high-performance adaptability.
Product Overview
Carboxylated iron oxide nanoparticles (DMSA@Fe₂O₃) are modified with carboxyl (-COOH) functional groups on the surface, which enhance their negative surface charge, water solubility, and stability. This modification provides excellent biocompatibility, making these nanoparticles suitable for various biomedical applications. The functionalized nanoparticles not only improve stability in biological systems but also offer multiple chemical functionalization sites for the conjugation and immobilization of biomolecules. These properties make them ideal for drug delivery, molecular probe construction, and other related applications.
