“…The authors observed that the fibers were pepsin resistant and stable in simulated gastric fluid (SGF), whereas they could be digested in a simulated intestinal fluid (SIF) to gradually release the incorporated compounds where they are normally absorbed [ 112 ]. In a further work [ 113 ], the same research group obtained the same material applying two physical approaches: (i) incorporation of surface-modified cellulose nanowhiskers (SCNs); and (ii) fiber alignment, to reinforce the assembled hordein/zein electrospun nanofabrics. The stability and mechanical properties of the modified fibers were evaluated in relation to the fiber morphology, and the structure was characterized by SEM, TEM, FTIR and Raman spectroscopy.…”

Zein is a biodegradable and biocompatible material extracted from renewable resources; it comprises almost 80% of the whole protein content in corn. This review highlights and describes some zein and zein-based materials, focusing on biomedical applications. It was demonstrated in this review that the biodegradation and biocompatibility of zein are key parameters for its uses in the food-packing, biomedical and pharmaceutical fields. Furthermore, it was pointed out that the presence of hydrophilic-hydrophobic groups in zein chains is a very important aspect for obtaining material with different hydrophobicities by mixing with other moieties (polymeric or not), but also for obtaining derivatives with different properties. The physical and chemical characteristics and special structure (at the molecular, nano and micro scales) make zein molecules inherently superior to many other polymers from natural sources and synthetic ones. The film-forming property of zein and zein-based materials is important for several applications. The good electrospinnability of zein is important for producing zein and zein-based nanofibers for applications in tissue engineering and drug delivery. The use of zein’s hydrolysate peptides for reducing blood pressure is another important issue related to the application of derivatives of zein in the biomedical field. It is pointed out that the biodegradability and biocompatibility of zein and other inherent properties associated with zein’s structure allow a myriad of applications of such materials with great potential in the near future.

“…One was the strong interactions, such as hydrogen bonds, between nanocrystals and cellulose matrix. Another was the increased alignment of cellulose chains in the fiber direction . Further increase of nanocrystal content would lead to the decrease of σ b .…”

“…CENC have great strength and axial elastic modulus, large specific surface area, high aspect ratio, low density, and a large number of hydroxyl side groups on the surface . Because of these unique properties, CENC have been used as reinforcements to improve the mechanical properties of poly(vinyl alcohol) (PVA) films, prolamin protein fibers, cellulose acetate film, bio‐based polyurethane, poly(lactic acid) composites, cellulose composites, acrylic composites, and other materials …”

In this study, regenerated cellulose fibers reinforced by cellulose nanocrystals (CENC) and chitin nanocrystals (CHNC) were prepared by blending the nanocrystals suspensions with the cellulose solution in NaOH/urea/water solvent at room temperature. The effect of nanocrystals' addition on the properties of spinning dopes and regenerated fibers were investigated and compared. Results showed that the obtained CENC and CHNC had different dimensions, and both of them increased the viscosity and decreased the transparency of the spinning dopes. However, the dissolution state of cellulose was not changed. CHNC had a greater influence on the properties of spinning dopes, while CENC had more obvious effect on the performance of regenerated fibers. The CENC reinforced fibers showed a higher crystallinity index as compared to the CHNC reinforced fibers. The tensile strength of the regenerated fibers was evidently improved when 3 wt % CENC or 2 wt % CHNC were added, while the elongation at break of the fibers was slightly decreased with the increase of nanocrystals content. The morphology and thermal stability of the regenerated fibers was not affected by the addition of nanocrystals. This study suggested that the dimension, group and content of nanocrystals were important factors for the reinforcement of regenerated cellulose fibers. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…The addition of cationically modified (using phenyltrimethylammonium chloride) CNC helped to increase the tensile strength, Young's modulus, water resistance, and alignment of the fibers. In addition, these fibers were encapsulated with a model drug (riboflavin) and were found to be effective for controlled release within a period of 24 h [39].…”

Nanocellulose has been used with promising results as reinforcement material in composites, many of which include hydrophobic polymers. However, the hydrophilic nature of nanocellulose can be better exploited in composites that incorporate high surface energy systems as well as in applications that can benefit from such properties. In fact, proteins can be ideal components in these cases. This paper reviews such aspects, which are based on the remarkable mechanical properties of nanocellulose. This material also exhibits low density, high aspect ratio, high surface area, and can be modified by substitution of its abundant hydroxyl groups. It also shows biocompatibility, low toxicity, and biodegradability. Convenient biotechnological methods for its production are of interest not only because of the possible reduction in processing energy but also because of positive environmental aspects. Thus, enzymatic treatments are favorable for effecting fiber deconstruction into nanocellulose. In addition to reviewing nanocellulose production by enzymatic routes, we discuss incorporation of enzyme activity to produce biodegradable systems for biomedical applications and food packaging. Related applications have distinctive features that take advantage of protein-cellulose interactions and the possibility of changing nanocellulose properties via enzymatic or protein treatments.
