Structure of this Review, which includes a brief introduction (panel 1, section 1) and introduces the relationship between chitin chemistry (section 2) and its deconstruction into nanochitin (panel 3, section 3). The Review also covers the main interactions (panel 4, section 4) that rule the multiscale structuring of nanochitin in a variety of media, resulting in diverse applications. The latter take advantage of multidimensional phenomena (panel 5, section 5). Finally, we present the promise of nanochitin in relation to industrialization and to accelerate materials development in the context of the bioeconomy (panel 6, section 6).
