Summary: The study synthesized undoped and Cobalt-doped zinc oxide nanoparticles (Co doped ZnO NPs) and confirmed the incorporation of the Co dopant through spectroscopic and microscopic techniques. The Co-doped ZnO NPs showed a red shift in the UV-absorption spectra and a decrease in band gap value, indicating successful integration of Co2+ ions into the ZnO matrix. The synthesized NPs exhibited excellent photocatalytic and antimicrobial activity, with 1% Co-doped ZnO showing the highest photocatalytic efficiency.

Summary: This study developed a sodium alginate/polyethylene oxide-based nanocomposite film loaded with nickel and zinc oxide nanoparticles, which enhanced its properties and antibacterial activity. The addition of nickel and zinc oxide nanoparticles improved the film's crystallinity, dielectric and electrical conductivity, mechanical properties, and antibacterial activity. The water solubility of the film decreased with the increase in nanoparticle content. The nanocomposite film has potential applications in antimicrobial food packaging.

Summary: Biosynthesized zinc oxide nanoparticles (ZnONPs) have gained attention for their safe and non-toxic nature and powerful antimicrobial characteristics. Microbes and plants have been used to synthesize ZnONPs in a facile, rapid, cost-effective, and non-toxic manner. The antimicrobial mechanisms of ZnONPs include the generation of reactive oxygen species, disruption of cell walls and membranes, and damage to DNA.

Summary: A novel synthetic approach for iron-doped zinc oxide nanoparticles was proposed for cancer cell treatment, showing potential as a multifunctional theranostic nanoplatform. The nanoparticles synthesized by a rapid wet-chemical method exhibited superior optical properties, novel magnetic responsiveness, and enhanced electromechanical behavior due to iron doping, which are expected to enhance therapeutic functionalities. Furthermore, the intrinsic therapeutic potentialities of the nanoparticles were tested in terms of cytotoxicity, cellular uptake, and biocompatibility for potential theranostic applications.

Summary: In this study, (Mn, Ni) co-doped ZnO catalyst was prepared using Stephania abyssinica leaf extract and characterized for its photocatalytic activity. The 5NMZO catalyst demonstrated the highest degradation efficiency, degrading 99.53% of MB dye. The superior photocatalytic activity of the 5NMZO catalyst can be attributed to its lower recombination rates of photo-generated electrons and holes, lower electron transfer resistance, larger surface area, and higher absorption capacity under visible light.

Summary: Human African trypanosomiasis is a serious infectious disease that requires urgent discovery of effective drugs. In this study, 12 compounds were isolated from Euphorbia abyssinica, and 1,6-di-O-galloyl-d-glucose showed the strongest activity against trypanosomal phosphofructokinase. Molecular dynamics simulations and ADMET calculations also supported its potential as a drug candidate. Further in vitro and in vivo studies are recommended.

Summary: The biocompatible nanocomposites were fabricated using chitosan and tragacanth gum with varying percentages of ZnO and ZnO@Ag nanoparticles. Characterization of the nanocomposites revealed the formation of hydroxyapatite on their surfaces. Evaluation of antibacterial activity showed that nanocomposites containing ZnO@Ag NPs exhibited stronger inhibition zones against Staphylococcus aureus and Escherichia coli compared to those containing ZnO NPs.

Summary: This study found that drinking water in developing countries is mainly contaminated by bacterial pathogens, emphasizing the necessity to investigate its suitability for consumption. The high proportion of individuals using unimproved sanitation facilities and practicing open defecation contributes to poor sanitation and contamination of public drinking water. Experimental analysis revealed that while some parameters of the water samples met WHO guidelines for drinking water, coliform bacteria exceeded the recommended limits in pipe water sources during the wet season.
