| titleOfInvention | Preparing method of three-dimensional chiral silver nanometer material |
| abstract | The invention belongs to the field of nanometer materials and optics, and provides a preparing method of a three-dimensional chiral silver nanometer material using DNA (deoxyribonucleic acid) frameworks as templates. According to the method, the DNA frameworks are used as templates for absorbing silver nanometer ions, and the silver nanometer ions are reduced into silver nanometer particles through reducing agents. The method concretely comprises the following steps that (1) DNA three-dimensional frameworks are prepared; (2) the DNA frameworks absorb the silver nanometer particles; (3) the silver nanometer ions which are not adsorbed are removed through ultrafiltration; (4) the silver nanometer particles are reduced through reducing agents. The problems of low assembling yield, nonuniform assembling body structure and the like during the preparation of chiral nanometer materials by using chiral molecules in the prior art are solved, and the preparing method of the three-dimensional chiral silver nanometer material using the DNA frameworks as the templates is provided. The method has the advantages that the growth dimension of the silver nanometer particles can be effectively controlled through regulating the concentration of the silver nanometer ions and the reducing agents in the system, and a transmission electron microscope result shows that the four silver nanometer particles are in spiral arrangement, so that the chiral signal resources are explained. |
