Green synthesis of CuO nanoparticles using Hibiscus sabdariffa L. extract to treat wastewater in Soba Sewage Treatment Plant, Sudan.

Looking for a cost-effective and ecofriendly method for wastewater treatment is a global challenge. Therefore, this study investigated the removal of wastewater pollutants using copper oxide nanoparticles (CuONPs). CuONPs synthesized by a green solution combustion synthesis (SCS) and characterized by ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FT-IR), powder X-ray diffraction analysis (PXRD), and scanning electron microscopy (SEM) techniques.

Encapsulation Capacity of β-Cyclodextrin Stabilized Silver Nanoparticles towards Creatinine Enhances the Colorimetric Sensing of Hydrogen Peroxide in Urine.

The β-cyclodextrin shell of synthesized silver nanoparticles (β) are found to enhance the detection of hydrogen peroxide in urine when compared to the Horse Radish Peroxidase assay kit. Nanoparticles are confirmed by the UV-Vis absorbance of their localized surface plasmonic resonance (LSPR) at 384 nm. The mean size of the β is 53 nm/diameter; XRD analysis shows a face-centered cubic structure.

Green Synthesis, Characterization, Antimicrobial, Anti-Cancer, and Optimization of Colorimetric Sensing of Hydrogen Peroxide of Algae Extract Capped Silver Nanoparticles.

A green and cost-effective technique for the preparation of silver nanoparticles (Algae-AgNPs) as a colorimetric sensor for hydrogen peroxide (HO) is described. Silver nanoparticles were capped using the green algae ) extract at an optimum time of 3 h at 80 °C. The pH of the plant extract (pH = 7.
