CTAB-modified gold nanoparticles offer optimized surface functionalization, superior colloidal stability, and enhanced plasmonic properties. Designed for advanced applications, they ensure efficient dispersion, extended durability, and high-performance adaptability.
Product Overview
CTAB-modified gold nanoparticles (CTAB-AuNPs) are stable nanoparticles formed by modifying the surface of gold nanoparticles with cetyltrimethylammonium bromide (CTAB). CTAB, a cationic surfactant, provides a positive charge, enhancing the stability and interaction of gold nanoparticles in biological systems. These nanoparticles are widely used in nanochemistry and biomedical applications.
Features
- Positive Surface Charge: CTAB imparts a positive charge to the gold nanoparticles, improving their stability and interactions in biological systems.
- High Stability: The long-chain alkyl groups of CTAB form a protective layer that prevents aggregation of the gold nanoparticles, improving their stability in aqueous media.
- Easy Dispersion: CTAB-modified gold nanoparticles are easily dispersed in water, making them suitable for aqueous-phase chemical reactions and biomedical applications.
Applications
- Biosensing: The surface plasmon resonance (SPR) properties of gold nanoparticles allow CTAB-modified gold nanoparticles to be used in biosensors for detecting molecular interactions.
- Biological Imaging: These nanoparticles can be used in optical and photoacoustic imaging, offering high-resolution imaging results.
- Photo-thermal Imaging and Sensing: CTAB-modified gold nanoparticles show excellent potential in photo-thermal imaging and sensing, making them widely applicable in related research and applications.
