Compared to traditional thiolated DNA probes, poly-adenine-based DNA probes (polyA DNA probes) are free of special chemical modifications, and thus exhibit unique advantages of easy synthesis, low economic cost, and excellent stability. Using their intrinsic polyA fragments, polyA DNA probes are combined onto the gold surface to form a compact and ordered monolayer with both anchoring and recognition capabilities. As a result, polyA DNA probes have attracted numerous research interests in biosensing. In this review, we first presented the mechanism of interaction between polyA DNA probes and the gold surface and then reviewed the applications of the polyA DNA probes in the development of biosensors, including colorimetric biosensors, fluorescence biosensors, surface-enhanced Raman scattering (SERS) biosensors, and electrochemical biosensors. We concluded with a discussion of the opportunities and challenges for polyA DNA probes and expected this review to be informative for the development of biosensors in food safety, environmental monitoring, and biomedicine.
