This study found that chitosan and surface-deacetylated chitin nanofibrils promoted hair growth in mice and increased fibroblast growth factor-7 production in human follicle dermal papilla cells.

In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.

Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.

This study found that dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

This study found that treating chitin from crab shells with ultrasonication at specific conditions effectively produced fine nanofibers with a high yield.
