“…Hence, biopolymers are considered promising materials with the advantages of renewability, degradability, edibility, and biocompatibility, for example, the lyocell fiber [7] and chitosan/ellagic acid films [1]. Moreover, biopolymers can be used as carriers of preservatives, antioxidants, and other substances to protect and improve food quality [8]. The edible film (packaging material) prepared by using a biopolymer is being developed rapidly because of its biodegradability and potential barrier properties to moisture and gases and reduced environmental pollution caused by the application of traditional plastic packaging [9].…”

This study was performed to estimate the effect of the incorporation of different cotton-nanocrystalline cellulose (C-NCC) contents with soy protein isolate (SPI) films. The results indicated that the C-NCC content had no effect on the thickness of the composite films ( 0.06 ± 0.01 mm ), and the optical property of the composite films decreased as the C-NCC contents increased. Water vapor, carbon dioxide, and oxygen permeability decreased with the introduction of C-NCC and started to increase when the peak of 7% C-NCC was reached. Water solubility of the SPI/C-NCC films decreased from 44.46% of the SPI films to 35.36% of the SPI/C-NCC films with 5% C-NCC. The tensile strength (TS) of films increased from 4.25 MPa to 6.02 MPa by increasing the C-NCC content from 0 to 7%. Then, the TS decreased as the C-NCC content was further increased. The trend of the elongation at break was opposite to that of the TS. The results from FTIR and DSC indicated that the addition of C-NCC did not change functional groups of the SPI films, and the glass transition temperature shifted toward a higher temperature as the C-NCC content increased. Hence, the addition of C-NCC enhanced the barrier and mechanical properties of the SPI/C-NCC composite films.

“…Therefore, CS, which is characterized by its long-lasting action, high adherence, and antibacterial properties, is an optimal additive for formulating composite films for practical applications. Kawasaki et al [15] prepared a CS/CMC nanofiber composite film, and demonstrated that the addition of CS effectively inhibited the growth and adhesion of bacteria, showing a vast potential for biomedical material applications. Further, Noshirvani et al [16] studied the influence of cinnamon and ginger essential oils on the physical and chemical properties of CS/CMC films.…”

A sodium alginate/chitosan solution was prepared by dissolving sodium alginate, chitosan, and glycerol in an acetic acid solution. This solution was then combined with a sodium carboxymethyl cellulose solution and the mixture was cast onto a glass plate and dried at a constant temperature of 60 • C. Then, a carboxymethyl cellulose/sodium alginate/chitosan composite film was obtained by immersing the film in a solution of a cross-linking agent, CaCl 2 , and air-drying the resulting material. First, the most advantageous contents of the three precursors in the casting solution were determined by a completely random design test method. Thereafter, a comprehensive orthogonal experimental design was applied to select the optimal mass ratio of the three precursors. The composite film obtained with sodium alginate, sodium carboxymethyl cellulose, and chitosan contents of 1.5%, 0.5%, and 1.5%, respectively, in the casting solution displayed excellent tensile strength, water vapor transmission rate, and elongation after fracture. Moreover, the presence of chitosan successfully inhibited the growth and reproduction of microorganisms. The composite film exhibited antibacterial rates of 95.7% ± 5.4% and 93.4% ± 4.7% against Escherichia coli and Staphylococcus aureus, respectively. Therefore, the composite film is promising for antibacterial food packaging applications.

“…2D CMC nanofibrous wound dressings have been extensively studied due to their microstructure similarity to intact skin tissue and extracellular matrix (ECM) and their high potential as drug carriers, liquid absorbents, and moisturizers. Various strategies can fabricate CMC nanofiber dressings, including ultrasonication, casting, freeze-drying, and electrospinning [91,104,105]. Electrospinning is the most widely used CMC nanofiber dressing fabrication technique due to its low costs, green fabrication, simplicity, reliability, and versatility [87,92,106,107].…”

Recent Advances in Cellulose-Based Structures as the Wound-Healing Biomaterials: A Clinically Oriented Review

et al. 2021

Application of wound-healing/dressing biomaterials is amongst the most promising approaches for wound repair through protection from pathogen invasion/contamination, maintaining moisture, absorbing exudates, modulating inflammation, and facilitating the healing process. A wide range of materials are used to fabricate wound-healing/dressing biomaterials. Active wound-healing/dressings are next-generation alternatives for passive biomaterials, which provide a physical barrier and induce different biological activities, such as antibacterial, antioxidant, and proliferative effects. Cellulose-based biomaterials are particularly promising due to their tunable physical, chemical, mechanical, and biological properties, accessibility, low cost, and biocompatibility. A thorough description and analysis of wound-healing/dressing structures fabricated from cellulose-based biomaterials is discussed in this review. We emphasize and highlight the fabrication methods, applied bioactive molecules, and discuss the obtained results from in vitro and in vivo models of cellulose-based wound-healing biomaterials. This review paper revealed that cellulose-based biomaterials have promising potential as the wound-dressing/healing materials and can be integrated with various bioactive agents. Overall, cellulose-based biomaterials are shown to be effective and sophisticated structures for delivery applications, safe and multi-customizable dressings, or grafts for wound-healing applications.
