Polyphenols are a class of ubiquitous compounds distributed in nature, with fascinating inherentbiocompatible, bioadhesive, antioxidant, and antibacterial properties. The unique polyphenolic structuresbased on catechol or pyrogallol moieties allow for strong non-covalent interactions (e.g., multiplehydrogen bonding, electrostatic, and cation–Π interactions) as well as covalent interactions (e.g., Michaeladdition/Schiff-base reaction, radical coupling reaction, and dynamic coordination interactions withboronate or metal ions). This review article provides an overview of the polyphenol-based scaffoldsincluding  the  hydrogels, films,  and  nanofibers that  have  emerged from  chemical  and functionalsignatures during the past years. A full description of the structure–function relationships in terms of  their  utilization  in  wound  healing,  bone  regeneration,  and  electroactive  tissue  engineering  isalso carefully discussed, which may pave the path towards the rational design and facile preparation ofnext-generation polyphenol scaffolds for tissue engineering applications
