Special Issue Information

Dear Colleagues,

Natural polymers, such as polysaccharides, proteins, and DNA, regulate key functions of biological systems owing to their sophisticated structures endowing them with extraordinary properties. The molecular functionalities of natural polymers, and their macromolecular structures and properties, provide inspiration for designing different classes of high-performance polymeric materials that aim to reproduce specific functions of natural polymers, such as adaptability, self-healing, adhesiveness, surface superwettability and superhydrophobicity, chiral recognition, and bioactivity. The field of bioinspired and biomimetic polymers is rapidly expanding in diverse technological sectors, including pharmacology, tissue engineering, the aerospace industry, optical materials and lightweight structural materials, and biosensors. Biomimetic synthetic polymers and hybrid polymer-materials have the advantage of combining desired functions with tailored morphology and superior chemical and physical stability.

Bioinspired and biomimetic polymers aims to cover all aspects of the subject, including, for instance, the synthesis of hybrid polymer/biomolecule conjugates and blends, self-assembling polymers, chiral polymers and surfaces, films, functional polymer brushes, nanocomposites and nanocomposite hydrogels, and supramolecular polymer structures, without forgetting studies of structure-property relationships, fabrication of materials with precise structural control and advanced properties, and applications of bioinspired polymers in all the different fields mentioned above.

This Special Issue welcomes reports on recent findings and reviews from experts in this frontier sector.

Abstract
Chiral polyamidoamino acids were obtained by polyaddition of N,N’-methylenebisacrylamide with d-, d,l- and l-tryptophan (M-d-Trp, M-d,l-Trp and M-l-Trp). l-tryptophan/glycine copolymers, M-G-l-Trp5, M-G-l-Trp [...] Read more.
Chiral polyamidoamino acids were obtained by polyaddition of N,N’-methylenebisacrylamide with d-, d,l- and l-tryptophan (M-d-Trp, M-d,l-Trp and M-l-Trp). l-tryptophan/glycine copolymers, M-G-l-Trp5, M-G-l-Trp10, M-G-l-Trp20 and M-G-l-Trp40, were prepared from l-tryptophan/glycine mixtures. These polymers were amphoteric, with acid-base properties similar to those of the parent amino acids. The l-tryptophan/glycine copolymers with high glycine content were water soluble in the pH range 2-12. M-G-l-Trp40 showed a solubility gap centred at pH 4.5 and all tryptophan homopolymers were soluble only at pH > 7. Dynamic light scattering measurements performed in their solubility ranges, namely 2-11 M-G-l-Trp5, M-G-l-Trp10 and M-G-l-Trp20 and 7-11 for M-G-l-Trp40, M-d-Trp, M-l-Trp and M-d,l-Trp, showed that the size of all samples did not significantly vary with pH. Both M-l-Trp and M-G-l-Trp copolymers showed pH-dependent circular dichroism spectra in the wavelength interval 200–280 nm, revealing structuring. All samples were fluorescent. Their emission spectra were unstructured and, if normalized for their tryptophan content, almost superimposable at the same pH, providing evidence that only tryptophan governed the photoluminescence properties. Changing pH induced in all cases a slight shift of the emission wavelength maximum ascribed to the modification of the microenvironment surrounding the indole ring induced by different protonation degrees.
