Summary
Peptoids, or poly(N-substituted glycine)s, offer biocompatible and tunable materials for advanced biomedical uses. Recent progress enables precise synthesis of anisotropic self-assemblies like nanotubes and nanosheets for applications in phototherapy and biosensing.
Area of Science:
- Polymer Chemistry
- Materials Science
- Biomedical Engineering
Background:
- Peptoids (poly(N-substituted glycine)s) are peptide mimics with tunable side chains, offering biocompatibility and precise synthesis.
- They form well-defined self-assemblies (vesicles, micelles, sheets, tubes) amenable to atomic-scale analysis.
- Recent research focuses on developing advanced peptoid-based materials for diverse applications.
Purpose of the Study:
- To review recent advancements in peptoid synthesis strategies.
- To highlight the development of one- and two-dimensional anisotropic peptoid self-assemblies.

Main Methods:
- Review of recent literature on peptoid synthesis and self-assembly.
- Analysis of techniques used to characterize peptoid nanostructures.
- Exploration of reported biomedical applications of peptoid self-assemblies.
Main Results:
- Peptoid side chain crystallization drives the formation of ordered anisotropic self-assemblies (nanotubes, nanosheets).
- Simple synthesis modifications allow fine-tuning of side chain properties like hydrophobicity and crystallinity.
- Protease resistance of peptoids enables stable nanostructures for biomedical use.
Conclusions:
- Anisotropic peptoid self-assemblies, including nanotubes and nanosheets, are readily synthesized and highly ordered.
