Biobased polymers such as chitin, composed of β-(1→4)-linked N-acetyl-d-glucosamine, and cellulose, composed of β-(1→4)-linked d-glucose, have emerged as versatile building blocks for bioderived soft nanomaterials, offering unique mechanical, optical, and interfacial properties. (1,2) Through controlled hydrolysis, chitin nanocrystals (ChNCs) and cellulose nanocrystals (CNCs) can be liberated from their native microfibrillar form.
