Abstract

The invention relates to the technical field of DNA nanotechnology, in particular to copper nanoclusters synthesized by applying a DNA nanoribbon template method, a synthesis method and application ofthe copper nanoclusters. According to the copper nanoclusters synthesized by applying the DNA nanoribbon template method, the synthesis method and the application of the copper nanoclusters, a DNA nanoribbon is synthesized by adopting a DNA origami technique, and the DNA nanoribbon is taken as a template to synthesize the copper nanoclusters; and the copper nano-clusters synthesized by applying the DNA nanoribbon template method are arranged more orderly, stable in fluorescence intensity, high in heat resistance, more excellent in performance, and are expected to show greater potential in theaspect of non-label fluorescence biological assay.

Description

technical field

[0001] The invention relates to the field of DNA nanotechnology, more specifically, a copper nanocluster synthesized by a DNA nanobelt template method, a synthesis method and an application thereof. Background technique

[0002] DNA origami technology uses the special base pairing mechanism of DNA to make DNA form highly ordered nanostructures through self-assembly, such as: complex two-dimensional objects, three-dimensional objects and surface patterns. With the increasingly perfect DNA origami technology, DNA is not only a kind of genetic material, but also a more complex structure and function of DNA has been developed.

[0003] Nanoclusters of noble metals such as gold, silver, and copper refer to clusters formed by dozens of metal atoms, usually with a diameter of about 2nm. Due to their excellent fluorescence properties, ultra-fine size, good biocompatibility, and low toxicity, Noble metal nanoclusters have attracted extensive attention in in vivo imag...
