Carboxylated Solid Silica Nanoparticles

Product Overview
Carboxylated solid silica nanoparticles are surface-functionalized silica particles with adjustable size, morphology, and microstructure, making them suitable for a variety of applications. Synthesized through the sol-gel method, these silica particles exhibit excellent dispersibility and tunable surface chemistry. They can undergo further functionalization, such as amino and carboxylation, to meet specific application needs. With broad potential in catalysis, adsorption, sensing, and biomedicine, these nanoparticles offer versatile and effective solutions across several industries.

Key Features

• Controllable Particle Size:The particle size can be precisely controlled by adjusting reaction parameters, such as precursor concentration, reaction time, and temperature.
• Good Monodispersity:The nanoparticles exhibit a uniform size distribution, ensuring stability and consistency across applications.
• Tunable Surface Chemistry:The surface can be functionalized (e.g., amino or carboxyl modification) to modify the chemical properties for specific applications.

Applications

• Chromatography Packing Materials:Due to their excellent monodispersity and chemical stability, these nanoparticles are ideal for use as stationary phase materials in high-performance liquid chromatography (HPLC) and gas chromatography (GC).
• Optical Materials:Utilized in the preparation of optical coatings and anti-reflection films to enhance the performance of optical devices.
• Coatings and Paints:Used to improve the wear resistance, corrosion resistance, and hardness of coatings and paints.
• Biomedical Applications:The functionalized nanoparticles can be modified with specific antibodies or ligands for selective cell separation. When combined with fluorescent dyes or quantum dots, they can be used for cell and tissue imaging.
