Chitosan-Cellulose Nanocrystal Polyelectrolyte Complex Particles: Preparation, Characterization, and In Vitro Drug Release Properties
… drugs. Cellulose nanocrystals were prepared by sulfuric acid hydrolysis of bleached wood pulp. Chitosans with three different molecular weights (81, 3·103, 6·103 kDa) and four different degrees of deacetylation (77, 80, 85, 89%) were used. PEC formation was studied by turbidimetric titration. …

Effects of acid hydrolysis conditions on cellulose nanocrystal yield and properties: A response surface methodology study
… nanocrystals (CNCs) are frequently prepared by sulfuric acid hydrolysis of a purified cellulose starting material. CNC yields, however, are generally low, often below 20%. This study employs response surface methodology to optimize the hydrolysis conditions for maximum CNC yield. Two …

The Potential of Cellulose Nanocrystals in the Detection and Treatment of Cancer
… stable and reproducible CNCs from wood pulp via sulfuric acid hydrolysis. Furthermore, we have functionalized the surface of these nanoparticles and conjugated them with the targeting ligand folic acid (FA) and the fluorescent imaging agent fluorescein-5\'-isothiocyanate (FITC) to create …

ECO-SUSTAINABLE PACKAGING MATERIALS FOR THE FOOD INDUSTRY (ECOPACKMAT)
… homogenization, HPH) and chemical (i.e., sulfuric acid hydrolysis) methods, respectively. All these products were thoroughly characterized and further tested - both internally (UNIMI) and at the industrial partner’s site (Fedrigoni S.p.a) – in different packaging configurations. …

Effects of the Non-ionic Surfactant Tween 80 on the Enzymatic Hydrolysis of Model Cellulose and Lignocellulosic Substrates
… non-ionic surfactant Tween 80 on the enzymatic hydrolysis of cellulose and LC substrates. Model cellulose substrates were prepared from cellulose nanocrystals (CNCs) obtained by sulfuric acid hydrolysis of wood pulp. Two methods were developed for the removal of the sulfate groups on the CNCs, …

Isolation of Cellulose Nanocrystals: Data-Driven Identification of Key Factors Affecting Yield and Morphology
… the treatment of cellulose fibres with sulfuric acid remains the most widely used. Although conceptually simple, this process involves a complex interplay of parameters that can significantly influence the yield and morphology of the resulting CNCs. However, many of these critical …
