Gold Nanopowder Water Dispersion (Au, 10–15 nm, 100ppm) is a liquid suspension of gold nanoparticles dispersed in water. Here’s a detailed breakdown of its features and applications:
- Key Features:
- Gold (Au): The material is gold, known for its excellent biocompatibility, conductivity, optical properties, and catalytic activity.
- Nanoparticles: The gold particles have an average size of 10–15 nanometers (nm), which results in enhanced reactivity due to their increased surface area and nanoscale effects.
- Water Dispersion: The nanoparticles are evenly dispersed in water to form a stable colloidal solution, preventing aggregation or settling.
- Concentration: The dispersion has a concentration of 100 ppm (parts per million), meaning there are 100 milligrams of gold nanoparticles per liter of solution.
- Properties:
- Small Particle Size: The 10–15 nm size provides enhanced surface reactivity, which makes the nanoparticles more efficient in catalytic and sensing applications.
- Stability: The dispersion is stabilized to ensure the gold nanoparticles remain uniformly distributed over time without clumping or settling.
- Optical and Catalytic Properties: Gold nanoparticles exhibit unique optical characteristics, such as surface plasmon resonance, which are useful in various applications, and high catalytic efficiency.
- Applications:
- Biomedical Applications: The gold nanoparticles are used in drug delivery systems, diagnostic imaging, and other biomedical technologies due to their biocompatibility and optical properties.
- Catalysis: Used as a catalyst in chemical reactions, especially in reactions requiring selective oxidation or other gold-catalyzed processes.
- Sensors: Employed in biosensors and chemical sensors for detecting specific molecules, utilizing the surface-enhanced optical properties of gold nanoparticles.
- Electronics: Applied in nano-scale electronic components and conductive coatings, as well as in sensors and flexible electronics.
- Handling and Safety:
- Toxicity: Gold nanoparticles are generally considered biocompatible, but care should still be taken to avoid inhalation or ingestion. Follow appropriate safety protocols.
- Storage: Store the dispersion in a cool, dark place to maintain its stability and prevent particle degradation.
- Precautions: Wear gloves, goggles, and lab coats when handling the dispersion, and work in a well-ventilated area or under a fume hood to avoid inhalation of any particles.
This material is widely used in advanced applications requiring the unique properties of gold nanoparticles, such as in medical technologies, electronics, and catalytic processes.
