We demonstrate the application of superlocalization microscopy to identify sequence-specific portions of single-stranded DNA (ssDNA) with sequence resolution of 50 nucleotides, corresponding to a spatial resolution of 30 nm. Super-resolution imaging was achieved using a variation of a single-molecule localization method, termed as “motion blur” point accumulation for imaging in nanoscale topography (mbPAINT). The target ssDNA molecules were immobilized on the substrate. Short, dye-labeled, and complementary ssDNA molecules stochastically bound to the target ssDNA, with repeated binding events allowing super-resolution. Sequence specificity was demonstrated via the use of a control, noncomplementary probe. The results support the possibility of employing relatively inexpensive short ssDNAs to identify gene sequence specificity with improved resolution in comparison to the existing methods.Keywords: biosensing; materials and biointerfaces; mbPAINT; optical mapping; single-stranded DNA; super-resolution microscopy;
