“…When the concentration of Zn 2+ goes up to 0.01 M, a pale precipitate appears. This could be explained due to more nanoparticles formed, leading to the aggregation of the larger size of nanoparticles [53,54]. Hence, the concentration of Zn 2+ in this study was 0.001, 0.01, and 0.1 M, respectively.…”

Surgical site infection (SSI), mainly caused by Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), is considered the most frequent complication in a surgical patient. Globally, surgical site infection accounts for 2.5%-41.9% and even higher rates in developing countries. SSI affects not only the patient’s health but also the development of society. Like previous reports, a surgical suture increases the hazard of SSI due to its structure. The antibacterial suture is the most effective solution to decrease the SSI. Due to some unique properties, nano-zinc oxide (ZnO NPs) is one of the promising antibacterial agents for coating on the suture. In this study, we aim to synthesize the ZnO NPs using Piper betle leaf extract and used it to coat the suture. The effect of synthesis parameters on the size and morphology of ZnO NPs was studied as well. The UV-Vis spectrum indicated the formation of ZnO NPs with λ max at around 370 nm. The volume of leaf extract plays a role in controlling the size and morphology of zinc oxide nanoparticles. The average particle size of as-synthesized ZnO NPs was around 112 nm with a hexagonal and spherical shape. Other than that, the results proved that ZnO NPs performed a high antibacterial activity against S. aureus and E. coli with its antibacterial effectiveness up to 5 days. The ZnO NP-coated sutures also exhibited a high performance on bacterial inactivation. With key findings, this study made a tremendous contribution to lowering the burden on medical services in terms of medical treatment cost in developing countries.

“…where F is the fractional attainment of equilibrium and equals qt/qe and k fd (min −1 ) is the film diffusion rate coefficient. By applying Equation (7) to the removal data at Fig. 13 and by plotting ln (1-F) versus t, a straight line was obtained with zero intercept for the Pb(II) removal by MWG ZnO NPs with acceptable R 2 value (0.938).…”

“…Among these nanomaterials zinc oxide nanoparticles (ZnO NPs) is considered to be one of the most used nanomaterials. ZnO NPs featured by the purity of their structure and the well-designed composition, large specific surface area and small, hollow, and layered structures, which has been used in different applications, such as corrosion inhibition [2], biomedical [3][4][5][6][7][8], food packaging [9], energy [10], textiles [11], antibacterial [12], water treatment through photocatalytic process [13,14], CO2 conversion [15,16], and adsorption of organic [17], and inorganic pollutants [18].…”

In this research work, different ZnO NPs were prepared via eco-friendly green route using Ziziphus jujuba leaves extract assisted by microwave. Eco-friendly prepared ZnO NPs characterized by different techniques, and the results confirmed the preparation of hexagonal wurtzite ZnO nanoparticles with different particle sizes. The prepared ZnO NPs were then used for the adsorption and removal of two different azo dyes; methyl orange (MO), and methylene blue (MB), as well as toxic Pb(II) ions, from a model solution and real samples. Influence of experimental conditions was explored, and the results showed that most of the MB, MO and Pb(II) could be removed from the model solution within few minutes, at ambient conditions using 15 mg ZnO NPs. The removal of the MB, MO and Pb(II) using ZnO NPs was studied kinetically and thermodynamically, and the results showed that the experimental data were best fitted using the pseudo-second-order kinetic models. The thermodynamics study showed that the process was spontaneous, with exothermic nature. Finally, the prepared ZnO NPs were used for the removal of MB, MO and Pb(II) in real wastewater sample, and high removal efficiency was presented.

“…[ 16 ] Released Zn 2+ from ZnO NPs and MOF‐5 can cause reactive oxygen species (ROS) formation in the extracellular and intracellular medium of bacteria. [ 17,18 ] By this fact, the contribution of ZnONPs in NCs as heparinized ZnONPs/polyvinylalcohol (PVA)/CMC demonstrated enhanced biocompatibility and antibacterial activities against Escherichia coli and Staphylococcus aureus after 1, 3, and 7 days incubation. In this study, heparin may have anti‐inflammatory and growth factor roles in the wound healing process.…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/mabi.201900362.The remedy for infected chronic wounds such as diabetic foot ulcers is more complicated particularly in the case of patients with an inefficient immune system. Also, fighting against microbial infections in the wound site by available antibiotics may not be effective because of emerging antibiotic resistance properties among pathogenic bacteria and fungi. Recently, applications of micro-and nanoformulations of biomaterials have demonstrated improved therapeutic abilities for wound dressings. In this way, carboxymethyl, dialdehyde, and 2,2,6,6-tetramethylpiperidine-1-oxyl-oxidized celluloses are common biomaterials having outstanding physicochemical and therapeutic properties compared to unmodified cellulose. Therefore, in this review, recent progress in the field of wound healing and antimicrobial activities of these derivatives are presented and discussed.
