Au-DNA self-assembled nanomachines can perform intelligent tasks such as sensing biomarkers and delivery of drug molecules through rational customization and programming. By virtue of their efficient signal amplification and flexible scalability, Au-DNA nanomachines have developed into one of the most promising nanodevices. In this review, we summarize the latest progress in Au-DNA self-assembled nanomachines for biosensing applications. First, the functional modules for building Au-DNA nanomachines are introduced. Subsequently, we summarize the biosensing applications of Au-DNA nanomachines with electrochemical or fluorescent signals as the output, respectively. Finally, we discuss the challenges and potential opportunities for Au-DNA nanomachines in biomedical applications.

We successfully designed a smart activatable nanomachine for cancer synergistic therapy. Photodynamic therapy (PDT) and chemotherapy can be activated by intracellular telomerase while anti-cancer drugs can be effectively transported into tumour cells. An Sgc8 aptamer was designed, which can specifically distinguish tumour cells from normal cells and perform targeted therapy.
