“…According to Pasquet, the antibacterial activity is significantly influenced by the concentration of Zn 2+ ions because a similar level of antibacterial activity against Pseudomonas aeruginosa was achieved using a ten‐times higher concentration of those ions than against Staphylococcus aureus . In other works it was mentioned that antibacterial properties are also shown by nanoparticles released from materials obtained by the “Green synthesis” method …”

The paper presents results of the studies on porous composites obtained using lyophilization method based on the solutions of the following polymers: chitosan, sodium alginate and polylactide, as well as ZnO-doped CaO-SiO 2 -P 2 O 5 bioglass.The researchers took the advantage of zinc ions demonstrating the bactericidal, immune-stimulating, and tissue-regenerating functions in the organism. The cytotoxicity of the composites was tested on L929 cells by means of the direct and the indirect contact method. The antibacterial properties were determined against the gram-negative bacteria Pseudomonas aeruginosa and the gram-positive bacteria Staphylococcus aureus at 24, 48 hours, and 7 days. The study demonstrated that changes due to cytotoxicity effect of the composites depend on the type of polymer and on the duration of contact with cells. The composite with polylactide was found to be the least toxic for L929 cells. ZnO added to the chemical composition of bioglass ensured bactericidal effects. The antibacterial properties of the composites depended on the ZnO content, bioglass grain size, polymer type, and composite microstructure. The composites presented in this paper are innovative as biomaterials for filling bone cavities because they can be a matrix for cells and have an antibacterial effect while supporting the regeneration of damaged tissue.

“…Besides the different application of NPs, anti-cancer effects of these materials have provided attractive horizon in the treatment of several cancers. Given that the utilization of NPs are related to anti-cancer impacts against a variety of malignancies (Ezhilarasi et al, 2016;Sangsefidi et al, 2017;Ezhilarasi et al, 2018). Nowadays, some of the semiconductor nanoparticles including ZnO, Dy 2 Ti 2 O 7 , CaWO 4 , CdTiO 3 , NdVO4, and TiO 2 have been considered as photocatalysis materials for purification of polluted waters (Zhang et al, 2000;Liu et al, 2014;Sobhani-Nasab and Sadeghi, 2016;Rahimi-Nasrabadi et al, 2016a;Rahimi-Nasrabadi et al, 2016b;Hosseinpour-Mashkani and Sobhani-Nasab, 2017).…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

“…From the literature survey, the synthesized nanoparticles (Nps) by greener approach methods are useful for pharmaceutical applications and waste water treatment [6]. The advantages of using plant extracts in Ag NPs fabrication is non-hazardous simplicity in scaling up synthesis [7]. In the current work, ZnO nanoparticles are prepared by a novel, simple, efficient, environment friendly and green route using Azadirachta indicagum extract, which plays as a fuel.…”

The preparation of zinc oxide and silver doped zinc oxide nanoparticles using zinc nitrates and silver nitrates as oxidizers and Azadirachta indica gum as a fuel via solution combustion method at 500 °C. The synthesized nanoparticles were characterized by XRD, FTIR, UV-DRS, SEM and TEM studies; these materials were tested for photoluminescence and photocatalytic activity studies. The PXRD data indicated that the synthesized nanoparticles confirmed as hexagonal phase with average crystallite size of 13.33 and 13.34 nm for ZnO and Ag-ZnO respectively. The SEM data revealed that, the material obtained is highly porous and honeycomb like structure. In the photocatalytic degradation of methylene blue, Ag-ZnO nanoparticles have shown the good photocatalytic activity than undoped ZnO nanoparticles. This is due to the presence of Ag on the surface of ZnO catalyst makes the catalyst more sensitive to light and reduce the electron hole recombination. Furthermore, we have also examined the photoluminescence studies for the synthesized materials and it has given the green emission by excitation at 380 nm. In this study, the green synthesis method will produces large quantity of nanomaterials with less time and low cost.
