Such smart polymers are the focus of increasing attention as they provide new solutions to many applications (e.g., drug delivery, nanotech-nology, tissue engineering and biotechnology). This review focuses on amino acid based polymers, mainly synthetic polypeptides that are obtained by ring-opening polymerization. These include polymers based on natural amino acids, synthetic or modified amino acids and N-alkylated glycine derivatives. Based on what is known about the behavior of natural proteins in response to temperature variations, this review provides a comprehensive overview of the state of the art of thermosensitive polypeptides through a de-tailed description i) of the structure/thermoresponsiveness relationship, ii) of the mechanisms involved at the molecular level, iii) of their possible applications both in materials science and in biomedical ap-plications.
