“…As presented in Table S2, the mechanical behavior of CNC4 was higher than that previously reported [5,30,31,[33][34][35]51,55,60,83] suggesting that CNC/CS films can be used in the food packaging industry.…”

In this study, green composite films based on cellulose nanocrystal/chitosan (CNC/CS) were fabricated by solution casting. FTIR, XRD, SEM, and TEM characterizations were conducted to determine the structure and morphology of the prepared films. The addition of only 4 wt.% CNC in the CS film improved the tensile strength and Young’s modulus by up to 39% and 78%, respectively. Depending on CNC content, the moisture absorption decreased by 34.1–24.2% and the water solubility decreased by 35.7–26.5% for the composite films compared with neat CS film. The water vapor permeation decreased from 3.83 × 10−11 to 2.41 × 10−11 gm−1 s−1Pa−1 in the CS-based films loaded with (0–8 wt.%) CNC. The water and UV barrier properties of the composite films showed better performance than those of neat CS film. Results suggested that CNC/CS nanocomposite films can be used as a sustainable packaging material in the food industry.

“…Despite these properties, CS has certain intrinsic limitations, including poor mechanical properties and uncontrolled swelling in water. To overcome these limitations, and improve the final properties of the 3D scaffold, CH nanoforms have been incorporated into CS matrix [24,30]. CH and CS have already been used in preclinical studies for wound healing [31] and bone regeneration [32].…”

Articular cartilage degeneration is one of the most common causes of pain and disability in middle-aged and older people. Tissue engineering (TE) has shown great therapeutic promise for this condition. The design of cartilage regeneration constructs must take into account the specific characteristics of the cartilaginous matrix, as well as the avascular nature of cartilage and its cells’ peculiar arrangement in isogenic groups. Keeping these factors in mind, we have designed a 3D porous scaffold based on genipin-crosslinked chitosan/chitin nanocrystals for spheroid chondral differentiation of human adipose tissue-derived mesenchymal stem cells (hASCs) induced in hypoxic conditions. First, we demonstrated that, under low oxygen conditions, the chondrospheroids obtained express cartilage-specific markers including collagen type II (COL2A1) and aggrecan, lacking expression of osteogenic differentiation marker collagen type I (COL1A2). These results were associated with an increased expression of hypoxia-inducible factor 1α, which positively directs COL2A1 and aggrecan expression. Finally, we determined the most suitable chondrogenic differentiation pattern when hASC spheroids were seeded in the 3D porous scaffold under hypoxia and obtained a chondral extracellular matrix with a high sulphated glycosaminoglycan content, which is characteristic of articular cartilage. These findings highlight the potential use of such templates in cartilage tissue engineering.

“…Properties of cellulose nanofibrils (CNF) depend on the vegetable raw materials and processing methods. Typically, the techniques employ different processes such mechanical disintegration (e.g., grinding, refining, and ultrasonication) (Barbash, Yaschenko, & Shniruk, ; Szymańska‐Chargot et al, ), as well as biological (with specific bacteria and enzymes) and chemical (with acids and alkalis) (Kaya et al, ; Mujtaba, Kaya, et al, ; Mujtaba, Salaberria, et al, ; Mujtaba, Sargin, & Kaya, ), to produce various types of CNF, which differ in morphology, crystallinity, and surface chemistry (Nechyporchuk, Belgacem, & Bras, ; Shak, Pang, & Mah, ; Zhang, Barhoum, Xiaoqing, Li, & Samyn, ).…”

Different types of nanoscale components are being tested in the food microencapsulation process, in order to ensure better barrier properties. Thus, this study aimed to evaluate the properties of spray‐dried microparticles containing sweet orange essential oil produced using gum Arabic and maltodextrin as wall materials incorporated with cellulose nanofibrils. Therefore, both cellulose nanofibrils (morphology) and microparticles (load capacity, moisture adsorption isotherms, X‐ray diffractometry, thermogravimetry, and morphology) were characterized. The treatments containing gum Arabic and cellulose nanofibrils showed better results regarding load capacity (17% w/w). The moisture adsorption isotherms showed that replacing gum Arabic by maltodextrin the equilibrium moisture of the microparticles with and without cellulose nanofibrils were decreased. The presence of cellulose nanofibrils increased the thermal stability of the microcapsules, while higher maltodextrin concentration decreased thermal stability. The microparticles had spherical morphology and roughened surface for all treatments. Therefore, cellulose nanofibrils have potential use for application in the spray‐drying process. Practical applications With the development of new technologies, there is great potential for encapsulation of blended polymeric formulations with an innovative approach in presence of nanoscale components. Cellulose nanofibrils offer structural and mechanical properties and act as a thickener and a physical barrier allowing stabilization of the interface oil/water, what contributes to the improvement of the properties of the essential oil microparticles.
