Abstract

The invention relates to a method for using DNA induction nanometer particles to form tree wire, wherein said method comprises that: 1, putting solution with nanometer metal particles into deoxyribonucleic acid solution decorated by 5' mercapto to be mixed; 2, adding dimethyl sulfoxide, triethyl ester phosphate, or tripropoxy silicane, etc, adding buffer solution, adding Na+ and Mg2+, or adding K+ and Mg2+; 3, laying to form the tree wire. The invention uses the DNA recognize function, to induce the nanometer particles to form the nanometer tree wire, via the DNA sequence and self-installment condition to adjust the angles of branch and main tree of nanometer tree, and the distance between branch distance. The invention can be used in DNA molecule device, etc.

Description

technical field

[0001] The invention belongs to the technical field of using a chemical self-assembly method to manufacture functional devices, and in particular relates to a preparation method for using DNA to regulate the assembly of nano particles to form regular structured nano tree wires. Background technique

[0002] DNA is not only the most basic substance of life inheritance, but also its unique molecular structure and characteristics have attracted the attention of the research fields of materials and information science. The secondary structure of DNA achieves self-assembly at the nanometer level (the diameter of the DNA double helix structure is 2nm, and the pitch is 3.4nm), and it is easy to control and design artificially (the elements that make up the nucleic acid molecule are only four nucleotides). Through the synergistic interaction between DNA or DNA and other building units, combined with molecular recognition and self-assembly properties, the development ...
