A minimal hybridization chain reaction (HCR) system using peptide nucleic acids

open access: yesChemical Science, 2021
The HCR represents a powerful tool for amplification in DNA-based circuitry and sensing applications, yet requires the use of long DNA sequences to grant hairpin metastability.

Sequence-Specific Recognition of Double-Stranded DNA by Peptide Nucleic Acid Forming Double-Duplex Invasion Complex

open access: yesApplied Sciences, 2022
Peptide nucleic acid (PNA) is an analog of natural nucleic acids, where the sugar-phosphate backbone of DNA is replaced by an electrostatically neutral N-(2-aminoethyl)glycine backbone.

Visible Light-Induced Templated Metathesis of Peptide–Nucleic Acid Conjugates with a Diselenide Bridge

open access: yesBiomolecules, 2023
The use of template molecules as chemical scaffolds that significantly influence the course of the reaction has recently been intensively studied. Peptide nucleic acids (PNA) are molecules that mimic natural nucleic acids.

An Introduction to Peptide Nucleic Acid [PDF]

open access: yesCurrent Issues in Molecular Biology, 1999
Peptide Nucleic Acid (PNA) is a powerful new biomolecular tool with a wide range of important applications. PNA mimics the behaviour of DNA and binds complementary nucleic acid strands. The unique chemical, physical and biological properties of PNA have been exploited to produce powerful biomolecular tools, antisense and antigene agents, molecular ...

The folding propensity of α/sulfono-γ-AA peptidic foldamers with both left- and right-handedness

open access: yesCommunications Chemistry, 2021
Controlling the helical structure of peptide foldamers requires detailed understanding of the relationship between primary and secondary structure. Here the effect of monomer stoichiometry and configuration on the helical structures of peptide nucleic ...

Peptide nucleic acids in materials science [PDF]

open access: yesArtificial DNA: PNA & XNA, 2012
This review highlights the recent methods to prepare PNA-based materials through a combination of self-assembly and self-organization processes. The use of these methods allows easy and versatile preparation of structured hybrid materials showing specific recognition properties and unique physicochemical properties at the nano- and micro-scale levels ...

Nucleic Acid Carriers Based on Precise Polymer Conjugates [PDF]

open access: yes, 2011
Polymer polydispersity, random conjugation of functional groups, and poorly understood structure–activity relationships have constantly hampered progress in the development of nucleic acid carriers.
