Abstract
Complexes composed of hydrogen tetrachloroaurate (III) trihydrate (HAuCl4⋅3H2O) and DNA were first formed for the syn- thesis of gold nanoparticle using a DNA template, which were validated using UV-Vis spectroscopy. The morphology of com- plexes were also characterized by scanning electron microscopy (SEM). DNA-mediated gold nanoparticles were synthesized by the chemical reduction of DNA-Au(III) complexes using hydrazine (N2H4) and sodium borohydride (NaBH4) as reducing agents. The effects of reducing agent types and their concentration on the formation of gold nanoparticles were investigated. The results showed that hydarazine was the most effective for the reduction of DNA-Au(III) complex. The DNA-mediated gold nanoparticles were characterized SEM, particle size analyzer (PSA), and transmission electron microscopy (TEM). Gold nanoparticles with 55~80 nm in diameter were formed by the aggregation of smaller gold nanoparticles ( ∼nm), which was confirmed in the DNA matrix.
