Earth produces 2.12 billion tons of total wastes annually and nearly 2 million tons of petroleum-based synthetic polymers each day. The majority of synthetic polymers were obtained by packaging applications. Biodegradable films(biofilms) can be a good alternative for pollution-creating synthetic polymers.Rice hull powder (RHP) as reinforcing fillers, polyvinyl alcohol (PVA) as matrix along with silver nanoparticles (AgNPs) were used to prepare the biofilms. By using the solution casting method, five samples of PVA/RHP (1-5 mM) AgNPs biofilms were fabricated and characterized using Fourier transform infrared (FT-IR), X-Ray Diffraction Analysis (XRD), field emission scanning electron microscope (FESEM), Thermogravimetric Analysis (TGA) and differential scanning calorimetry beyond testing for their mechanical and antibacterial activities. The small spherical shape elements in the FESEM images clarify the presence of AgNPs. The intensities of observed peaks in the FT-IR spectrum keep decreasing with the inclusion of AgNPs. The X-ray diffractogram confirms the strong peaks at 2θ = 38.2 , 49.1 , 60.8 , & 78.3 due to the presence of the AgNPs. The tensile strength and tensile modulus reached a maximum value of 35.5 and 871 MPa respectively. The presence of heat-stable metallic silver made the biofilms thermally stable up to 371 C and also improved the antibacterial activity exhibited by a better inhibition zone. The improved results clarified that biofilms can be suggested for packaging applications.

“…From Figure 12, it is noticed that the pure PVA film has not formed any inhibition zone due to poor antibacterial activity. [ 44 ] The incorporation of RHP fillers in the PVA film created improved antibacterial activity by showing a better inhibition zone (Table 5).…”

“…Nanoparticles, including inorganic nanoparticles (such as clay, HAp, graphene, and metallic nanoparticles), organic/polymeric nanoparticles, and organic/inorganic nanoparticles, can be used as fillers to reinforce the matrix and bring the polymer new functionalities as well [115,116]. For example, Liang et al designed modern flaxseed gum (FG) nanocomposites for the slow release of iron [117].…”

The engineering of tissues under a three-dimensional (3D) microenvironment is a great challenge and needs a suitable supporting biomaterial-based scaffold that may facilitate cell attachment, spreading, proliferation, migration, and differentiation for proper tissue regeneration or organ reconstruction. Polysaccharides as natural polymers promise great potential in the preparation of a three-dimensional artificial extracellular matrix (ECM) (i.e., hydrogel) via various processing methods and conditions. Natural polymers, especially gums, based upon hydrogel systems, provide similarities largely with the native ECM and excellent biological response. Here, we review the origin and physico-chemical characteristics of potentially used natural gums. In addition, various forms of scaffolds (e.g., nanofibrous, 3D printed-constructs) based on gums and their efficacy in 3D cell culture and various tissue regenerations such as bone, osteoarthritis and cartilage, skin/wound, retinal, neural, and other tissues are discussed. Finally, the advantages and limitations of natural gums are precisely described for future perspectives in tissue engineering and regenerative medicine in the concluding remarks.

“…on the polymer chains allow a large amount of liquid to penetrate between the polymer chains to a level at which they can break, causing the hydrogel to dissolve. Therefore, many studies have investigated improvements in the entrapment capacity of the absorbed liquid by cross-linking the hydrogels with various compounds such as graphene oxide (GO) [ 7 , 8 , 9 , 10 , 11 ], copper compounds [ 12 , 13 , 14 , 15 ], alkaline salts [ 16 , 17 ], nanoparticles [ 18 , 19 , 20 , 21 ], and organic acids [ 22 ]. In addition, these materials impart specific properties that allow hydrogel formulations to meet desired application requirements such as antimicrobial properties, which are mandatory for food packaging [ 7 , 14 , 23 ], UV-VIS barriers for light-sensitive food [ 23 , 24 ], or water and gas barriers [ 23 ] to extend the shelf-life of food.…”

This study presents a structural analysis of a whey and gelatin-based hydrogel reinforced with graphene oxide (GO) by ultraviolet and visible (UV-VIS) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The results revealed barrier properties in the UV range for the reference sample (containing no graphene oxide) and the samples with minimal GO content of 0.66×10−3% and 3.33×10−3%, respectively, in the UV-VIS and near-IR range; for the samples with higher GO content, this was 6.67×10−3% and 33.33×10−3% as an effect of the introduction of GO into the hydrogel composite. The changes in the position of diffraction angles 2θ from the X-ray diffraction patterns of GO-reinforced hydrogels indicated a decrease in the distances between the turns of the protein helix structure due to the GO cross-linking effect. Transmission electron spectroscopy (TEM) was used for GO, whilst scanning electron microscopy (SEM) was used for the composite characterization. A novel technique for investigating the swelling rate was presented by performing electrical conductivity measurements, the results of which led to the identification of a potential hydrogel with sensor properties.
