Assessment of the Alga Cladophora glomerata as a Source for Cellulose Nanocrystals [PDF]

, 2023
Nanocellulose is isolated from cellulosic fibers and exhibits many properties that macroscale cellulose lacks. Cellulose nanocrystals (CNCs) are a subcategory of nanocellulose made of stiff, rodlike, and highly crystalline nanoparticles.
