The effect of nanoparticles on pulmonary fibrosis: a systematic review and Meta-analysis of preclinical studies
Arch Environ Occup Health. 2022 Mar 4:1-11. doi: 10.1080/19338244.2021.2001637. Online ahead of print.ABSTRACTAir pollution is a big ecumenical problem associated with public health around the world. The rapid development of nanotechnology worldwide resulted in a significant increase in human exposure with unknown particles, and ultimately leading to an increase in acute and chronic diseases. The effect of nanoparticles on pulmonary fibrosis has been reported in vivo and in vitro studies; however, the results are inconsistent. The present systematic review and meta-analysis of animal preclinical studies was conducted to as...

Synthesis and characterization of γ-ferric oxide nanoparticles and their effect on Solanum lycopersicum.
Abstract γ-Ferric oxide nanoparticles are synthesized through modern and facile ayurvedic route followed by normal and special purification steps, which are both cost-effective and eco-friendly. These synthesized γ-ferric oxide nanoparticles were applied on Solanum lycopersicum to search the effect on chlorophyll content. This process involves multiple filtration and calcination steps. The synthesized samples were analyzed by X-ray diffraction (XRD), UV-visible (UV-vis) spectroscopy, transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), and particle size analysis (PSA) to identify the puri...

Use of Co < sub > 3 < /sub > O < sub > 4 < /sub > nanoparticles with different surface morphologies for removal of toxic substances and investigation of antimicrobial activities via in vivo studies
Environ Sci Pollut Res Int. 2023 Sep 21. doi: 10.1007/s11356-023-29879-7. Online ahead of print.ABSTRACTCo3O4 nanoparticles (NPs) were formed using hydrothermal synthesis method and various surfactants to study the effect of changing surface morphology on catalytic and antibacterial activities. FT-IR, TEM, SEM, BET, XRD, and XPS analyses were performed to characterize the NPs. It was observed that as the morphology of Co3O4 changes, it creates differences in the reduction efficiency of organic dyes and p-nitrophenol (p-NP), which are toxic to living organisms and widely used in industry. The reaction rate constants (Kapp) ...

IJERPH, Vol. 14, Pages 747: Disinfection of the Water Borne Pathogens Escherichia coli and Staphylococcus aureus by Solar Photocatalysis Using Sonochemically Synthesized Reusable Ag@ZnO Core-Shell Nanoparticles
Water borne pathogens present a threat to human health and their disinfection from water poses a challenge, prompting the search for newer methods and newer materials. Disinfection of the Gram-negative bacterium Escherichia coli and the Gram-positive coccal bacterium Staphylococcus aureus in an aqueous matrix was achieved within 60 and 90 min, respectively, at 35 °C using solar-photocatalysis mediated by sonochemically synthesized Ag@ZnO core-shell nanoparticles. The efficiency of the process increased with the increase in temperature and at 55 °C the disinfection for the two bacteria could be achieved in 45 and 60 min, ...
