Abstract: DNA tetrahedral nanostructure is a kind of DNA three-dimensional nanostructure with tetrahedral shape, which is formed by precise and ingenious DNA sequence design, applying the principle of base complementary pairing and automatic hybridization of four single strands. It has good biocompatibility, excellent cell membrane permeability, simple preparation, high yield, adjustable size and dynamics, so it has been widely studied and applied in the fields of microbial identification, medical diagnosis and biosensors. Based on this, DNA tetrahedral nanostructures and their functional modification were introduced, and the application progress of DNA tetrahedral nanostructures in biotechnology was summarized, in order to provide reference for promoting the research of DNA tetrahedral nanostructures and broadening their application fields.

Key words: DNA tetrahedral structure, DNA nanotechnology, microbial identification, medical diagnosis, biosensor
