Raw images and processed datasets (NeuronJ tracings) of micron-scale nanofibers through self-assembly of gamma-modified peptide nucleic acids in 75% DMSO: water mixture. Images relate to understanding the propensity of these self-assembled nanostructures to grow into micron-sized nanofibers and are related to histogram plots (Fig 2b, Supplementary fig 7) and otherwise representative datsets (fig 2a, 3a-f, 4a) of related article submitted to Nature communications (2020) titled "Modular self-assembly of gamma-modified peptide nucleic acids in organic solvent...
