• Biomedical and Life Sciences: Gold dispersions are widely used in medical diagnostics (like rapid tests), drug delivery systems, imaging techniques, and cancer treatments. Their biocompatibility and unique optical properties make them ideal for targeting, visualizing, and treating diseases. 
• One of the most common uses is in lateral flow tests, where gold nanoparticles provide a visible red line that indicates a positive result—thanks to their strong light-scattering properties.
• Chemical and Biological Sensing: Gold nanoparticles are excellent for sensing applications because they change color when they aggregate or interact with specific molecules. This property is used in sensors for detecting chemicals, toxins, and biological markers.
• Catalysis: Gold dispersions act as efficient catalysts at the nanoscale, especially for oxidation and environmental reactions. Their high surface area and reactivity make them valuable in industrial and research-based chemical processes.
• Electronics and Photonics: In electronics, gold nanoparticles contribute to the development of nano-circuits and conductive materials. Their plasmonic behavior is also exploited in photonic devices for manipulating light at the nanoscale.
• Coatings and Materials Science: Gold dispersions are incorporated into coatings and materials for their aesthetic, antibacterial, and optical properties, enhancing the functionality and value of products like paints, inks, and surface treatments.

Handling and Storage

Gold nanoparticle dispersion contains no additional chemical reagents, ensuring a clean formulation. It should be stored away from direct sunlight and handled only by professionals with under suitable storage conditions. If agglomeration occurs after long-term storage, the dispersion can easily be re-homogenized by mixing prior to use.
