Cytotoxicity properties of plant-mediated synthesized K-doped ZnO nanostructures

Cytotoxicity evaluation of environmentally friendly synthesis Copper/Zinc bimetallic nanoparticles on MCF-7 cancer cells

“…Physical and chemical methods are mainly dependent on expensive and toxic equipment and reagents (Benkai et al 2016 ; Rahdar et al 2022 ; Wang et al 2021 ). Since there are major problems in the methods of physical and chemical synthesis of nanostructures, it is essential to use safe, cost-effective methods without applying harmful chemical compounds (Haghighat et al 2021 ; Li et al 2020 ; Zhang et al 2022 ). In the meantime, the biosynthesis approach has been reported as an easy, environmentally friendly and cost-effective method for the synthesis of nanoparticles using plant extracts.…”

RETRACTED ARTICLE: Biosynthesis of Zn-doped CuFe2O4 nanoparticles and their cytotoxic activity

“…Recent developments in science 18 – 28 and technology 29 – 39 even in engineering 40 – 42 , epidemiology 43 – 49 , mathematics 50 – 54 and geometry 55 – 58 have significant impact on human health 59 – 61 and life 62 – 68 . Nanoparticles (NPs) with different shapes 69 – 73 and sizes have been widely fabricated via a large number of physicochemical and bio-based synthesis techniques 74 , including electron irradiation, chemical reduction 75 , 76 , sol gel 77 , microwave-assisted synthesis 78 , and plant-mediated synthesis techniques 79 – 82 . However, there are still several challenging issues regarding their stability, aggregation/sedimentation, size distribution, and control of morphology 83 – 85 .…”

Highly basic and active ZnO–x% K2O nanocomposite catalysts for the production of methyl ethyl ketone biofuel

“…According to the abovementioned and illustrated results, the use of pure ZnO as pure or modified with 1–10% K 2 O calcined at 400°C for 3 h in oxygen, the following remarks can be summarized as follows: Because of its high activity, ZnO is a multitalented, flattering oxide in many processes 1–24 . ZnO as pure and modified catalysts were easily prepared herein and characterized by their nanoscale crystallite size in, that is, 22.9–28.0 nm, high basicity (ca.…”

“…Much attention has been focused on its technological applications in solar cells, 14–16 piezoelectric nanogenerators and force sensors, 17 and varistor ceramics 18 . Due to the wide range of technological applications of ZnO, recently, various preparation techniques have been developed 19–24 . Few years ago, we investigated the catalytic properties of various ZnO samples prepared from different precursors, 25 namely Zn(CH 3 CO 2 ) 2 ·2H 2 O, Zn 3 (C 6 H 5 O 7 ) 2 ·2H 2 O and Zn(NO 3 ) 2 ·6H 2 O, during the decomposition of ethanol.…”
