The most commonly used clinical methods are enzyme-linked immunosorbent assay (ELISA) and quantitative PCR (qPCR) in which ELISA was applied for the detection of protein biomarkers and qPCR was especially applied for nucleic acid biomarker analysis. Although these constructed methods have been applied in wide range, they also showed some inherent shortcomings such as low sensitivity, large sample volume and complex operations. At present, many methods have been successfully constructed on the basis of DNA nanotechnology with the merits of high accuracy, rapid and simple operation for cancer biomarkers assay. In this review, we summarized the bioassay strategies based on DNA nanotechnology from the perspective of the analytical attributes for the first time and discussed and the feasibility of the reported strategies for clinical application in the future.

Restriction-modification (R-M) systems protect against phage infection by detecting and degrading invading foreign DNA. However, like many prokaryotic anti-phage defences, R-M systems pose a major risk of autoimmunity, exacerbated by the presence of hundreds to thousands of potential cleavage sites in the bacterial genome. Pseudomonas aeruginosa strains experience the temporary inactivation of restriction endonucleases following growth at high temperatures, but the reason and mechanisms for this phenomenon are unknown.

Liver cancer, particularly hepatocellular carcinoma (HCC), poses significant treatment challenges due to chemoresistance and cancer recurrence. Similar to customs at the border, the liver detoxifies incoming chemicals via efflux pumps and overexpresses ATP-binding cassette (ABC) drug exporters, leading to chemoresistance. ABC contains a multihomosubunit structure and a revolving transport mechanism, actively effluxing drugs from cancer cells, thereby reducing intracellular drug accumulation and therapeutic efficacy.

Ferritin is a shell-like carrier protein with an 8 nm diameter cavity that naturally provides a space for encapsulating food and drug components. In the absence of iron atoms bound to this protein, it is called apoferritin, the form used in this study. However, its vulnerability to environmental conditions when used alone warrants further investigation.

DNA sequencing using nanopores is now well established. Could the approach be extended to proteins ? There are a number of difficulties but work by many groups has shown proof-of-principle solutions for most of them. Further progress could indeed lead to a workable protein sequencing approach that would have many applications in research and in the clinic.

Anisotropic gold nanoparticles (AuNPs) exhibit unique physicochemical properties that render them highly valuable for diverse applications. However, precise control over their growth direction and number of branches is challenging with conventional synthesis methods. A DNA origami-templated enzymatic synthesis strategy addresses this limitation.
