Abstract:
The biological application of labeled nanoparticles is a rapidly developing area of nanotechnology that raises new possibilities in the diagnosis and treatment of human cancers. Gold nanoparticles (GNPs) have been prepared via wet chemical method. Fluorescein capped gold nanoparticles have been prepared by a reduction of the HAuCl4 in boiling fluorescein sodium solution. The results indicated that the spectrum exhibits one curve with two absorption bands at
