As a result of this reaction, the colour of the solution changes from orange to brown, thus indicating the successful formation of AuNPs. The aforementioned Turkevich and Brust methods are primarily used for synthesizing spherical AuNPs. However, for the production of AuNPs with various geometries ...
Hibiscus leaf extract was used to synthesise gold nanoparticles of different size and shape with average particle size of 13 nm. On addition of extract to metal salt solution, colour of solution changes due to surface plasma resonance of gold nanoparticles. The UV–visible spectra of colloidal sol...

(about 700 nm) is reflected, producing a rich red colour. The wavelength of surface plasmon resonance-related absorption moves to longer, redder wavelengths as particle size rises. This results in solutions that have a light blue or purple colour because red light is absorbed and blue light is...
