Peptide Nucleic Acids: From Origami to Editing

Abstract

Peptide nucleic acids (PNAs) combine the programmability of native nucleic acids with the robustness and ease of synthesis of a peptide backbone. These designer biomolecules have demonstrated tremendous utility across a broad range of applications, from the formation of bespoke biosupramolecular architectures to biosensing and gene regulation. Herein, we explore some of the key developments in the application of PNA in chemical biology and biotechnology in the last 5 years and present anticipated key areas of future development.
