Far-field super-resolution fluorescence microscopy has allowed observation of biomolecular and synthetic nanoscale systems with features on the nanometre scale, with chemical specificity and multiplexing capability. DNA-PAINT (DNA-based point accumulation for imaging in nanoscale topography) is a super-resolution method that exploits programmable transient hybridization between short oligonucleotide strands, and allows multiplexed, single-molecule, single-label visualization with down to ~5-10 nm resolution. DNA-PAINT provides a method for structural characterisation of nucleic acid nanostructures with high spatial resolution and single-strand visibility.
