The present study found that gold
nanoparticles with nanosizes below 100 nm can be synthesized by a
wet-chemical route, carried out by induced autocatalytic method. The
successive liking of the neighboring nanoparticles seeds by
benzenedimethanethiol (BDMT) followed by the induced reduction of Au
(III) ions leads to the formation of well defined nanostructure
assembly. The size and shape of gold nanoparticles were relatively
achieved in a good uniformity. Surface analysis and imaging techniques
provided a direct evidence for the successful fabrication of the gold
nanostructure. Electrochemical measurements revealed that all of the
nanoparticles surfaces are not involved in the adsorption of BDMT.
Key words:
Gold nanostructure, benzenedimethanethiol (BDMT), imaging techniques,
electrochemical measurements, radiation therapy
