Custom-built DNA nanostructures are now used in applications such as biosensing, molecular computation, biomolecular analysis, and drug delivery. While the functionality and biocompatibility of DNA makes DNA nanostructures useful in such applications, the field faces a challenge in making biostable DNA nanostructures. Being a natural material, DNA is most suited for biological applications, but is also easily degraded by nucleases. Several methods have been employed to study the nuclease degradation rates and enhancement of nuclease resistance. This protocol describes the use of gel electrophoresis to analyze the extent of nuclease degradation of DNA nanostructures and to report degradation times, kinetics of nuclease digestion, and evaluation of biostability enhancement factors. © 2020 Wiley Periodicals LLC.
