Gold Nanopowder Water Dispersion (Au, 10–15 nm, 500ppm) is a highly concentrated colloidal solution of gold nanoparticles suspended in water. Here’s a detailed breakdown of its features and applications:
- Key Features:
- Gold (Au): The primary component is gold, renowned for its excellent biocompatibility, optical properties, and catalytic activity.
- Nanoparticles: The gold particles have an average size of 10–15 nanometers (nm), which enhances their reactivity and functionality due to their high surface area and nanoscale properties.
- 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 500 ppm (parts per million), meaning there are 500 milligrams of gold nanoparticles per liter of the solution.
- Properties:
- Small Particle Size: The 10–15 nm size ensures enhanced surface reactivity, which increases the effectiveness of the nanoparticles in a wide range of applications, such as catalysis and sensing.
- Stability: The dispersion is stabilized to prevent the nanoparticles from clumping or settling over time, ensuring uniformity in the solution.
- Optical and Catalytic Properties: Gold nanoparticles exhibit distinct optical properties, including surface plasmon resonance, which is useful for sensing applications. They also have high catalytic activity for certain chemical reactions.
- Applications:
- Biomedical Applications: Due to their biocompatibility, gold nanoparticles are widely used in drug delivery systems, diagnostic imaging, and other biomedical technologies.
- Catalysis: The gold nanoparticles serve as effective catalysts in a variety of chemical reactions, particularly in selective oxidation and other gold-catalyzed processes.
- Sensors: Gold nanoparticles are used in the development of biosensors and chemical sensors, where their optical properties are enhanced for the detection of specific analytes.
- Electronics: The nanoparticles are used in nanoelectronics for conductive coatings, flexible electronic components, and other advanced electronic devices.
- Handling and Safety:
- Toxicity: While gold nanoparticles are generally considered biocompatible, proper precautions should still be taken to avoid inhalation, ingestion, or contact with the skin.
- Storage: To maintain stability, the dispersion should be stored in a cool, dark environment.
- Precautions: Always use personal protective equipment, such as gloves, goggles, and lab coats, when working with the dispersion. It is also important to work in a well-ventilated area or under a fume hood to prevent exposure to airborne particles.
The higher concentration of 500 ppm provides a more significant dose of active gold nanoparticles, making it particularly effective for applications that require a stronger or more concentrated solution.
