Silica-coated silver nanoparticles offer optimized stability, superior antibacterial properties, and enhanced conductivity. Designed for advanced applications, they ensure efficient dispersion, extended durability, and high-performance adaptability.
Product Overview
Silica-coated silver nanoparticles (Ag@SiO₂) are nanocomposites with a core-shell structure, where silver nanoparticles form the core and a silica shell tightly encapsulates them. The silica shell not only enhances the chemical stability of the silver nanoparticles, preventing reactions with external chemicals, but also imparts improved physical, chemical, and optical properties. By adjusting the thickness and morphology of the silica shell, the performance of these nanoparticles can be precisely controlled. These nanoparticles are suitable for a variety of applications in fields such as biomedicine, optical sensing, and drug delivery.
Product Features
- Chemical Stability: The silica shell increases the chemical stability of the silver nanoparticles, preventing reactions with environmental factors and maintaining their inherent properties.
- Optical Properties: The silica shell affects the optical characteristics of the silver nanoparticles, especially the surface plasmon resonance (SPR) wavelength. By adjusting the shell thickness and morphology, their optical properties can be finely tuned.
- Antibacterial Properties: Silver nanoparticles are known for their excellent antibacterial performance. The silica shell further enhances this effect, especially with mesoporous silica-coated silver nanoparticles, which exhibit superior antibacterial efficacy and longevity.
- Biocompatibility: Ag@SiO₂ nanoparticles have good biocompatibility, making them suitable for in vivo applications without causing immune or toxic reactions. This gives them significant potential for biomedical use.
Applications
- Antibacterial Materials: These nanoparticles can be used to produce antibacterial coatings, antimicrobial textiles, and antimicrobial plastics, with applications in medical devices, food packaging, and household products.
- Biosensing: Leveraging the optical properties of Ag@SiO₂ nanoparticles, highly sensitive biosensors can be developed to detect biomolecules, ions, and other target substances.
