    Abstract Peptide nucleic acids (PNAs) have primarily been used to achieve therapeutic gene modulation through antisense strategies since their design in the 1990s. However, the application of PNAs as a functional nanomaterial has been more recent. We recently reported thatγ‐modified peptide nucleic acids (γPNAs) could be used to enable formation of complex, self‐assembling nanofibers in select polar aprotic organic solvent mixtures. Here we demonstrate that distinctγPNA strands, each with a high density ofγ‐modifications can form complex nanostructures at constant temperatures within 30 minutes. Additionally, we demonstrate DNA‐assisted isothermal growth ofγPNA nanofibers, thereby overcoming a key hurdle for future scale‐up of applications related to nanofiber growth and micropatterning.
