Novel Leea grandifolia leaves mediated synthesis of ZnO nanorods for photocatalytic and anticancer applications

Abstract

The main goal of this study was to use a green‐mediated approach for obtaining ZnO nanorods (NRs) using the Leea grandifolia leaf extract. The obtained ZnO NRs were studied using standard methods such as X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy with energy‐dispersive X‐ray analysis, Brunauer–Emmett–Teller, and transmission electron microscopy (TEM), and the results revealed a smaller particle size with a high surface area. The scanning electron microscopy and TEM results showed that the obtained particles were having rod‐like morphology with size ranging from ~20 to ~200 nm. The results of the antioxidant and photocatalytic studies showed excellent photodegradation and free radical scavenging. The results of the in vitro toxicological study revealed that the obtained particles were nontoxic to organisms. The cytotoxicity and genotoxicity assessments concluded that the NR‐treated MCF‐7 had gone through necrosis and apoptosis. The ZnO NRs revealed excellent antibacterial activity towards various pathogens. It was clear that the green‐mediated method could be considered as a better one for the synthesis of ZnO NRs as it imparts excellent anticancer, antibacterial, and photocatalytic properties.

Citric Acid-Mediated Microwave-Hydrothermal Synthesis of Mesoporous F-Doped HAp Nanorods from Bio-Waste for Biocidal Implant Applications

“…The Zebrafish ( Danio rerio ) is one of the best models widely used to evaluate the toxicity of biomaterials due to its transparent features and it has similarities to the human genome [ 65 ]. The toxicity evaluation was performed based on the standard OECD guidelines.…”

Green Synthesis of Magnesium Oxide Nanoparticles by Using Abrus precatorius Bark Extract and Their Photocatalytic, Antioxidant, Antibacterial, and Cytotoxicity Activities

“…Furthermore, it was allowed for imaging of the obtained sample. The absorption wavelength was analyzed through the exposure of synthesized MgO NPs by using a UV–Vis spectrophotometer (Cary 8454; Agilent Technologies, Singapore), which was analyzed by using the visible and infrared frequency range of 180–800 nm [ 20 ].…”
