Creating a sustainable and effective approach to handling organic contaminants from industrial waste is an ongoing problem. In the present study, ZnO nanoparticles (ZnO NPs) were synthesized under a controlled ultrasound cavitation technique using the extract of Passiflora foetida fruit peels, which act as a reducing (i.e., reduction of metal salt) and stabilizing agent. The formation of monodispersed and hexagonal morphology (average size approximately 58 nm with BET surface area 30.83m2/g). The synthesized ZnO NPs were characterized by a various technique such as UV–visible spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), Thermogravimetric analysis (TGA) and Dynamic light scattering (DLS). Further, the XRD pattern confirmed the hexagonal wurtzite structure of synthesized ZnONPs. The ZnO NPs exhibit excellent degradation efficiency towards organic pollutant dyes, i.e., Methylene blue (MB) (93.25% removal) and Rhodamine B (91.06% removal) in 70 min, under natural sunlight with apparent rate constant 0.0337 min−1 (R2 = 0.9749) and 0.0347 min−1 (R2 = 0.9026) respectively.Zeta potential study shows the presence of a negative charge on the surface of ZnO NPs. The use of green synthesized ZnO NPs is a good choice for wastewater treatment, given their high reusability and photocatalytic efficiency, along with adaptability to green synthesis.

“…CeO2NPs of different shapes and sizes have been created by microorganisms over the past few decades, along with other nanoparticles. Synthesizing CeO2NPs from microbes is an environmentally benign and cost-effective method [50,51]. CeO2NPs bulk salt is reduced and stabilized into matching NanoParticles primarily by enzymes and proteins, as well as their heterocyclic derivatives.…”

Green Synthesized Cerium oxide nanoparticles (CeO2NPs) have sparked a lot of interest in numerous disciplines of science and Technology during the past decade. A wide range of biological resources has been employed in synthesizing CeO2NPs, including plants, microorganisms, and other biological products. Biosynthesis procedures, current knowledge, and prospects in the synthesis of Green synthesis of CeO2NPs are also discussed. Neurodegenerative diseases, such as aging, trauma, Alzheimer's and Parkinson's, and other neurological problems, are linked to higher oxidative stress and superoxide radicals generation. Cerium oxide nanoparticles' antioxidant properties suggest that they may be useful in the treatment of CNS diseases. The biological antioxidant benefits of cerium oxide nanoparticles on extending cell and organism lifespan, preventing a free radical attack, and preventing trauma-induced neurological damage are discussed in this section. CeO2NPs, an aspect of nanotechnology, would emerge as a novel drug delivery carrier through therapeutic strategies. In several diseases oxidative stress and inflammation. CeO2NPs exhibited a remarkable ability to switch between+3 and+4 oxidation states making this an efficient therapeutic option and an effective drug delivery agent. Further Reactive oxygen and nitrogen species. The overall goal of this study is to provide reasonable insight into CeO2NPs as new therapeutic agents and to solve the challenges, of safely and effectively employing these CeO2NPs for efficient management of Central Nervous System diseases.

The effort of copper nanoparticle exploration for antibacterial cleaning agents needs to prevent infection or contamination of microorganisms such as bacteria and viruses due to its potential characteristic as an environmentally benign material. The synthesis of copper nanoparticles using 0.02 M Cu(NO3)2 as a precursor and red dragon fruit extract as a bioreduction agent has been conducted. The extraction process of red dragon fruit was done by the maceration method using methanol as solvent. Copper nanoparticles were prepared through green chemistry with the reduction method. The compound in red dragon fruit extract reduced Cu2+ to Cu. The experimental nanoparticle synthesis method was performed with a combination of red dragon fruit extract and Cu(NO3)2 solution mixed with a volume ratio of bioreductor extract toward Cu2+ precursor variation of 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, and 1:9. The mixtures were stirred using a magnetic stirrer for 30 minutes and then incubated. The samples were characterized using UV-Vis (Ultraviolet-Visible), FTIR (Fourier Transform Infrared), and a digital microscope to observe morphology. The observation continued to assess its antibacterial activity and potency as an active disinfectant. UV-Vis analysis showed that the absorbance value for 30 minutes tended to be stable. Particle size estimation showed the smallest size of 122.12 nm at a volume ratio of 1:9. Functional group analysis using FTIR showed a shift in wavenumber between dragon fruit extract and copper nanoparticle (CuNPs), indicating a functional group interaction. The results of morphological analysis using a digital microscope showed that the particles with fine powder granules were produced with the composition of fruit extract: Cu(NO3)2 of 1:9. Antibacterial activity against Staphylococcus aureus and Escherichia coli indicated that the composition of Cu-nanoparticles of 1:9 had given an inhibition value.
