Amino-Functionalized Solid Silica Nanoparticles

Product Overview
Amino-functionalized solid silica nanoparticles are surface-modified silica particles with tunable size, morphology, microstructure, and surface functionality. Synthesized via the sol-gel method, these particles have extensive applications in catalysis, adsorption, sensing, and biomedicine. The amino groups on the surface of these particles can be further modified to meet the specific requirements of different applications, such as coupling with other molecules or materials for functional applications.

Key Features

• Controllable Particle Size:The size of the silica nanoparticles can be precisely adjusted by controlling reaction parameters such as precursor concentration, reaction time, and temperature.
• Good Monodispersity:The particles exhibit uniform size distribution, ensuring high efficiency and performance across various applications.
• Tunable Surface Chemistry:The surface can be further functionalized (e.g., amino, carboxyl groups) to meet the needs of different 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:Used in the fabrication of optical coatings and anti-reflection films to enhance the performance of optical devices.
• Coatings and Paints:Enhance 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.
