They are typically prepared using a sodium citrate reduction method, also known as the seed-growth method. The size of the gold nanoparticles directly affects the color of the solution. As the particle size increases, the absorption wavelength of the solution shifts toward longer wavelengths, resulting in different color characteristics.<\/p>\n<p><strong>Features<\/strong><\/p>\n<ul>\n<li><strong>Optical Properties<\/strong>: Exhibits surface plasmon resonance, producing specific absorption and scattering spectra.
