Gold Nanoparticles (1)

Gold nanoparticles are minuscule gold particles with diameters ranging from a few nanometers to several hundred nanometers. Their small size and high surface-area-to-volume ratio grant them distinctive optical, electrical, and catalytic properties. These nanoparticles find applications in areas such as catalysis, sensing, and imaging, thanks to their interactions with light and other molecules. Additionally, they are utilized in the creation of materials like composites and coatings, where their specialized properties serve specific functions. The expanding field of nanotechnology has spurred growing research and development efforts focused on gold nanoparticles for diverse uses.
