DNA-templated preparation of gold nanoparticles |
| 초록 |
DNA-mediated gold nanoparticles were prepared by chemical reduction of DNA-Au (Ⅲ) complex. The DNA-Au (Ⅲ) was first formed by reacting DNA with HAuCl4 at the pH of 5.6. The complex in solution was reacted with hydrazine reducing Au (Ⅲ) to Au. The reduced Au formed aggregates of nano dimensions. The distributions of particles were obtained by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). This method resulted in a rather uniform dispersion of Au nanoparticles of near-spherical shape. Gold nanoparticles were surrounded and stabilized by DNA. |
