| titleOfInvention | A kind of DNA-guided gold-silver bimetallic nanoparticle and its preparation method and application |
| abstract | The invention provides a DNA-guided gold-silver bimetallic nanoparticle and a preparation method thereof. The preparation method includes the following steps: firstly, hairpin DNA molecules are modified on the surface of gold nanospheres to obtain gold nanospheres/hairpin DNA complexes, and then gold nanospheres/hairpin DNA complexes are prepared. The sphere/hairpin DNA complex was used as the seed. In the solution system, silver nitrate was in situ reduced by a reducing agent on the seed surface to grow into gold-silver bimetallic nano-mushrooms. The present invention also provides the hairpin DNA-directed gold-silver bimetallic nanoparticles obtained by the preparation method, which are in the form of core-shell-like or partially-coated mushroom-like shapes in which silver is completely covered with gold. Compared with the prior art, the preparation method of hairpin DNA as a template to form gold-silver bimetallic nano-mushroom particles according to the present invention has the advantages of mild reaction conditions, easy realization, low preparation cost, and can regulate the morphology and performance of gold-silver bimetallic nanoparticles. Advantages, the metal nanoparticles of the present invention have a good application in inhibiting the growth of bacteria. |
