“…As the % loading of GSE the transparency of the prepared membranes is decreased. The reason for the decrease in transparency for GSE loaded membranes is that GSE concentration and the thickness of the membranes (see Table 2 ) also one of the important reasons for the decrease in the optical transparency [ 46 ].…”

“…This behavior may be due to increased flexibility of the membrane materials as the % loading of GSE increases in the polymer matrix. The prepared membranes are flexible because of the internal hydrogen bonding and increase the intermolecular spacing [ 46 , 49 ]. The obtained results show that as the GSE content in the blend polymeric membrane increases, so does the elongation at break.…”

The poly(vinyl alcohol) (PVA) and starch-based polymeric films with a ratio of 2:8 were prepared using solution casting followed by a solvent evaporation method. Four types of membranes with varied concentrations of grapefruit seed extract (GSE) i.e., 2.5–10 wt% was incorporated in the films. The prepared membranes were assessed for transparency test, mechanical properties, surface morphology, permeability test for O 2 , and antimicrobial properties. The PVA/starch-10% GSE loaded film showed excellent mechanical properties showing highest 1344 ± 0.7% elongation at break but poor optical transparency with 53.8% to 68.61%. The Scanning Electron Microscopic study reveals the good compatibility between the PVA, Starch, and GSE. The gas permeability test reveals that the prepared films have shown good resistance to the O 2 permeability 0.0326–0.316 Barrer at 20 kg/cm 2 feed pressure for the prepared membranes showing excellent performance. By adding the little amount of GSE into the PVA/starch blend membranes showed promising antimicrobial efficacy against MNV-1. For 4 h. incubation, PVA/starch blend membranes containing 2.5%, 5%, and 10% GSE caused MNV-1 reductions of 0.92, 1.89, and 2.27 log PFU/ml, respectively. Similarly, after 24 h, the 5% and 10% GSE membranes reduced MNV-1 titers by 1.90 and 3.26 log PFU/ml, respectively. Antimicrobial tests have shown excellent performance to resist microorganisms. The water uptake capacity of the membrane is found 72% for the PVA/starch pristine membrane and is reduced to 32% for the 10% GSE embedded membrane. Since the current pandemic situation due to COVID-19 occurred by SARSCOV2, the prepared GSE incorporated polymeric blend films are the rays of hope in the packaging of food stuff.

“…This study was carried out to better understand the ability of the developed nanocomposite membranes to perform antimicrobial activity. ZnO NP's were tested for antimicrobial activity three times [31][32]. A fruits like orange and black grapes were used as used as the control, and an inhibited zone was discovered against E. Coli and S. aureus, and the fruit part was severely affected by these microorganisms, as shown in figure 4.One can clearly infer from the above figure that ZnO nanoparticles distributed in the prepared PDA media was least affected.…”

The most cutting-edge field of the twenty-first century is nanotechnology. In comparison to their bulk counterparts, nanoparticles have grown significantly in importance due to their special features. Zinc oxide nanoparticles are among the most significant metal nanoparticles because they are used in optical, physical, and antibacterial characteristics, gas sensors, biosensors, cosmetics, medication delivery systems, and other products. ZnO NPs can be created via a variety of chemical processes, including the hydrothermal process, vapor transfer method, and precipitation method. Due to its great biocompatibility, affordability, and low toxicity, ZnO NPs have grown to become one of the most widely used metal oxide nanoparticles in biological applications over the past 20 years. By adjusting the growth temperature and precursor concentration, the hydrothermal technique was used to create stable, OH free zinc oxide (ZnO) nanoparticles. Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray diffraction (XRD) results supported the formation of ZnO nanoparticles. It has been determined that the typical particle size is between 60 and 80 nm by particle size measurement using zeta sizer. By creating an agar-agar culture plate, ZnO nanoparticles as adsorbent materials were evaluated for the antimicrobial test by taking different microbial species. The zone of inhibition study was proved that ZnO nanoparticles were successful in limiting the bacterial growth in the petriplate culture media. According to experimental findings, among the chosen materials, ZnO NPs have demonstrated the best antifungal activity.

“…Polymers based on HEMA were first mentioned in a study from 1936 [ 2 ], but only after 1960 when Wichterle and Lim [ 28 ] obtained the first hydrogel based on HEMA, was a way opened for the preparation of new types of hydrogels with various chemical structures being designated for use in biomedical applications. In recent years, semi-IPNs consisting of crosslinked networks based on HEMA and linear polymers that can be natural (alginate, selacan, chitosan, hyaluronic acid, chondroitin sulphate) or synthetic (poly(vinyl alcohol), poly(N-vinylpyrrolidone)) have been prepared and used in different applications [ 29 , 30 , 31 , 32 , 33 ]. Regarding the semi-IPNs based on HEMA and another synthetic polymer, the information is quite limited.…”

Semi-interpenetrating polymer networks (semi-IPN) represent a type of polymeric material that has gained increasing amount of interest for their potential biomedical application. This study presents the synthesis, characterization and tetracycline loading/release capacities of semi-IPNs based on hydroxyethyl methacrylate (HEMA) and poly(4-vinylpyridine) (P4VP) or poly (1-vinyl-4-(1-carboxymethyl) pyridinium betaine) (P4VPB-1) and poly (1-vinyl-4-(2-carboxyethyl) pyridinium betaine) (P4VPB-2). The optimization of the semi-IPNs synthesis was achieved by studying the influence of reaction parameters (chemical structure of the cross-linking agent, HEMA:crosslinker ratio, HEMA:linear polymers ratio and the type of solvent of the linear polymers) on the yield of obtaining semi-IPNs and swelling capacity of these systems. Fourier-transform infrared analysis and scanning electron microscopy highlighted the chemical structures and morphologies of the semi-IPNs. The higher swelling capacity was observed in the case of the PHEMA/P4VPB-2 network due to the increased hydrophilicity of P4VPB-2 compared with P4VP and P4VPB-1 polymers. In vitro release studies of tetracycline reveal that the release mechanism is represented by non-Fickian diffusion being controlled by both diffusion and swelling processes. The antimicrobial activity of semi-IPN–tetracycline systems was tested against E. coli and S. aureus, demonstrating that tetracycline is released from the semi-IPN and retains its bactericidal activity. An increased value of the inhibition zone diameter compared with that of tetracycline indicates the possibility that the semi-IPN containing P4VPB-2 also exhibits intrinsic antimicrobial activity due to the presence of the polybetaine in the network structure.
