Green nanotechnology for preserving and enriching yogurt with biologically available iron (II)

The use of biological selenium nanoparticles to suppress Triticum aestivum L. crown and root rot diseases induced by Fusarium species and improve yield under drought and heat stress

“…The BioSeNPs exhibited considerable antioxidant activity ( Gunti et al, 2019 , Kapur et al, 2017 , Shubharani et al, 2019 , Vyas and Rana, 2017 ), because of the occurrence of phenolic compounds and flavonoids content in the nanoparticles suspension besides, their small size ( Huang et al, 2007 ), these active compounds are derived from the rich bacterial media especially yeast extract in LB media ( El-Saadony et al, 2021b , Vieira et al, 2016 ). The scavenging activity significantly increased in the concentration-dependent matter ( Shubharani et al, 2019 ).…”

Impact of mycogenic zinc nanoparticles on performance, behavior, immune response, and microbial load in Oreochromis niloticus

“…Microbes are potent eco-friendly Nano factories and can control the size and shape of biological nanoparticles ( Reda et al, 2021 , El-Saadony et al, 2021a ,b). The biological Synthesis of metallic nanoparticles, can be split into two categories, bioreduction and biosorption.…”

“…ZnONPs can be synthesized using several methods such as physical, chemical, and biological methods (by microbes or plants). The biological synthesis of NPs is safe, clean, biocompatible, and eco-friendly besides, the fast reduction of metal ions at ambient conditions of temperature unlike physical or chemical methods, they consume extensive energy or use toxic solvents, respectively ( El-Saadony et al, 2020a , Akl et al, 2020 , El-Saadony et al, 2019 , El-Saadony et al, 2021a , El-Saadony et al, 2021b ). From the biological methods used for the synthesis of NPs, fungus-mediated procedure gained great importance ( Thakkar et al, 2010 ).…”

Polyphenolic extracts from pomegranate and watermelon wastes as substrate to fabricate sustainable silver nanoparticles with larvicidal effect against Spodoptera littoralis

“…Synthesis of nanoparticles using physical and chemical methods is costly, has adverse impacts on the environment and needs high energy ( El-Saadony et al, 2018 , El-Saadony et al, 2019 , El-Saadony et al, 2020 ). On the other hand, biosynthesis of nanoparticles is considered a clean and an economic alternative route when fabricated using bacteria ( Reda et al, 2020 , Sheiha et al, 2020 , El-Saadony et al, 2021a , Reda et al, 2021 ), fungi ( El-Saadony et al, 2021b ) and plants is cheaper and favors large-scale production, as it requires simpler downstream processing. The application of botanicals for the synthesis of nanostructured materials offers numerous benefits than the use of safe chemicals in the synthesis ( Borase et al, 2014 ).…”
