“…Ag-NPs, ZnO-NPs, and CuO-NPs are very effective against microorganisms and find numerous biomedical applications. [25,[32][33][34][35] Aluminum oxide nanoparticles (AlO-NPs) are important for the ceramic industry as an absorbent to reinforce the composite metal matrix. AlO-NPs are commonly used for protective surface coating, catalyst, construction materials, and composites and biomedical uses, which include wound healing treatment.…”

This study focuses on the synthesis of aluminum oxide nanoparticles (AlO-NPs) hydrogel through in situ method and formation of biopolymer nanocomposite film. UV-Vis spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy (TEM), particle size analyzer, and energy dispersive X-ray spectrum were performed for the characterization of AlO-NPs. TEM micrograph demonstrates the presence of AlO-NPs in the range of 50-100 nm in the hydrogel network made from sugarcane bagasse carbo-xymethyl cellulose (SB-CMC) and synthetic carboxymethyl cellulose (CMC). The successful absorptions peak at 210 nm while conducting UV-Vis spectroscopy suggests existence of AlO-NPs. The antibacterial properties of AlO-NPs were analyzed using the disc plate diffusion technique against Gram-negative bacteria:Escherichia coli (ATCC 433); and Gram-positive bacteria: Bacillus subtilis (ATCC 1688). AlO-NPs present in CMCs films reduce moisture content, solubility; elongation at break and increases films' tensile strength.

“…Augustine and Rajarathinam showed that a combination of Ag NPs with alginate reduced the toxicity of the silver ions released from silver nanoparticles and improved wound healing [40]. The same effect was observed in CMC by Kumar et al [41] and Prema et al [42]. Unfortunately, there is a growing bacterial resistance to silver, which is alarming when searching for new antibiotics.…”

To solve the problem of human diseases caused by a combination of genetic and environmental factors or by microorganisms, intense research to find completely new materials is required. One of the promising systems in this area is the silver-silica nanocomposites and their derivatives. Hence, silver and silver oxide nanoparticles that were homogeneously distributed within a silica carrier were fabricated. Their average size was d = (7.8 ± 0.3) nm. The organic polymers (carboxymethylcellulose (CMC) and sodium alginate (AS)) were added to improve the biological features of the nanocomposite. The first system was prepared as a silver chlorine salt combination that was immersed on a silica carrier with coagulated particles whose size was d = (44.1 ± 2.3) nm, which coexisted with metallic silver. The second system obtained was synergistically interacted metallic and oxidized silver nanoparticles that were distributed on a structurally defective silica network. Their average size was d = (6.6 ± 0.7) nm. Physicochemical and biological experiments showed that the tiny silver nanoparticles in Ag/SiO2 and Ag/SiO2@AS inhibited E. coli, P. aeruginosa, S. aureus, and L. plantarum’s cell growth as well as caused a high anticancer effect. On the other hand, the massive silver nanoparticles of Ag/SiO2@CMC had a weaker antimicrobial effect, although they highly interacted against PANC-1. They also generated reactive oxygen species (ROS) as well as the induction of apoptosis via the p53-independent mechanism.

“…Cellulose is linear in shape and high-molecular-weight polymer and due to the presence of intermolecular and intramolecular-OH bonding; it barely mixed freely in common solvents. CMC is highly water-soluble polysaccharide formed by mercerization (sodium hydroxide) and etherification (Monochloroacetic acid) process [10,11]. CMC is white in color, odorless, tasteless, non-toxic, free-flowing powder, biodegradable, biocompatible, hydrophilic, and good film forming agent [12,13].…”

The current study stresses on the reuse of waste lignocellulose biomass (rice husk and sugarcane bagasse) for the synthesis of carboxymethyl cellulose (CMC) and further conversion of this CMC into a biodegradable film. Addition of commercial starch was done to form biodegradable film due to its capacity to form a continuous matrix. Plasticizers such as Glycerol and citric acid were used to provide flexibility and strength to the film. Biopolymer film obtained from sugarcane bagasse CMC showed maximum tensile strength and elongation in comparison to the film synthesized from commercial CMC and CMC obtained from rice husk. It has been observed that an increase in sodium glycolate/NaCl content in CMC imposed an adverse effect on tensile strength. Opacity, moisture content, and solubility of the film increased with a rise in the degree of substitution of CMC. Therefore, CMC obtained from sugarcane bagasse was better candidate in preparing biopolymer/biocomposite film.
