Abstract. Bromination is herein exploited to promote the emergence of elastic behavior in a short peptide—SDSYGAP—derived from resilin, a rubber-like protein exerting its role in the jumping and flight systems of insects. Elastic and resilient hydrogels are obtained, which also show self-healing behavior, thanks to the promoted non-covalent interactions that limit deformations and contribute to the structural recovery of the peptide-based hydrogel. In particular, halogen bonds may stabilize the β-sheet organization working as non-covalent cross-links between nearby peptide strands. Importantly, the unmodified peptide (i.e., wild type) does not show such properties. Thus, SDSY(3,5-Br)GAP is a novel minimalist peptide elastomer.

Lorenzo Sori, Dr. Andrea Pizzi, Prof. Giancarlo Terraneo, Prof. Pierangelo Metrangolo and others have recently published an article on CrystEngComm about "Hydrogen and halogen bond synergy in the self-assembly of 3,5-dihalo-tyrosines: structural and theoretical insights".

Abstract. Halogenation, generally introduced on aromatic amino acids, is becoming a key supramolecular tool in peptides. Herein, we report the crystal structures and DFT study of two bis-halogenated tyrosines showing the subtle relationship between hydrogen and halogen bonds in promoting their supramolecular self-assembly.

The SupraBioNano resreach group is glad to announce its 1^st School of Supramolecular and Bio-Nanomaterials!

The field of supramolecular systems and bio-nanomaterials is both timely and highly interdisciplinary and this School wishes to foster a collaborative, multidisciplinary, and dynamic “playground” for presenting and discussing the most recent research results in field of supramolecular chemistry and self-assembled materials.

This School aims to provide a research-led overview of the current state-of-the-art in self-assembly phenomena, applied supramolecular chemistry, and bio-nanomaterials. Taking inspiration from Nature, the attendees will be guided through all aspects of chemistry underpinning the formation of hierarchical structures and complex functionalities.

The School is designed for PhD students, Post-Docs, and young scientists with various fields of interest, who aim at mastering the phenomena associated with molecular recognition and self-assembly, and the design and preparation of functional molecules and materials for a wide-range of high-end applications. During an intense training week the attendees will learn how to design and develop functional materials through the combination and assembly of organic, inorganic, coordination, biological molecules, and higher-level building units.

Welcome to the 1^stSchool
