- Abstract
The observation of DNA nanodevices at a single molecule (i.e., device) level and in real time provides rich information that is typically masked in ensemble measurements. Single-molecule fluorescence resonance energy transfer (smFRET) offers a means to directly follow dynamic conformational or compositional changes that DNA nanodevices undergo while operating, thereby retrieving insights critical for refining them toward optimal function. To be successful, smFRET measurements require careful execution and meticulous data analysis for robust statistics. Here we outline the elemental steps for smFRET experiments on DNA nanodevices, starting from microscope slide preparation for single-molecule observation to data acquisition and analysis., (© 2023.
