Core-shell silver@gold nanoparticles provide optimized plasmonic properties, superior stability, and enhanced biocompatibility. Designed for advanced applications, they ensure efficient light manipulation, extended durability, and high-performance adaptability.
Product Overview
Core-shell silver@gold nanoparticles are a type of nanomaterial where the core is composed of gold nanoparticles, and the shell is made of metallic silver. These particles exhibit excellent dispersion and stability and can be tailored to meet specific requirements for both the core and shell sizes. Silver@gold nanoparticles are widely used in surface-enhanced Raman spectroscopy (SERS) substrates, food safety testing, and antibacterial products.
Key Features
- Excellent Dispersion and Stability: The surface of the nanoparticles carries a negative charge, ensuring superior dispersion and long-term stability.
- High Surface Area: With a large surface area and high loading capacity, these nanoparticles are well-suited for surface functionalization, allowing customization for various applications.
- Adjustable Size: The core-shell structure of the gold-silver nanoparticles allows flexibility in adjusting the size of the core and shell to meet specific application needs.
Applications
- Surface-Enhanced Raman Spectroscopy (SERS) Substrates: Thanks to their unique optical properties, silver@gold nanoparticles are widely used as SERS substrates for enhanced Raman signal detection.
- Food Safety Testing: These nanoparticles can be employed in detecting harmful substances in food, offering a sensitive and efficient detection method.
- Antibacterial Products: Leveraging the antimicrobial properties of silver, core-shell silver@gold nanoparticles are used as antibacterial agents in medical and everyday consumer products.
