Green synthesis of Ag@AgCl/Elaeagnus angustifolia seed nanocomposite using Elaeagnus angustifolia leaves: an amazing nanophotocatalyst with highly photocatalytic activity under sunlight irradiation
“…Phytofabricated eco-friendly silver nanoparticles showed higher bactericidal, antioxidant, and anti-inflammatory activities [ 14 ]. In addition, several authors reported the fabrication of silver chloride nanoparticles (AgClNPs) or hybrid Ag/AgClNPs from plant extracts [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Such Ag/AgCl plasmonic hybrids have antibacterial properties with low cytotoxicity, which may be attributed to the solubility equilibrium of Ag + controlled by AgCl that allows for a low Ag + level to be released into the environment [ 18 , 19 ].…”
Silver/silver chloride nanoparticles (Ag/AgClNPs), with a mean size of 48.2 ± 9.5 nm and a zeta potential value of −31.1 ± 1.9 mV, obtained by the Green Chemistry approach from a mixture of nettle and grape extracts, were used as “building blocks” for the “green” development of plasmonic biohybrids containing biomimetic membranes and chitosan. The mechanism of biohybrid formation was elucidated by optical analyses (UV–vis absorption and emission fluorescence, FTIR, XRD, and SAXS) and microscopic techniques (AFM and SEM). The aforementioned novel materials showed a free radical scavenging capacity of 75% and excellent antimicrobial properties against Escherichia coli (IGZ = 45 mm) and Staphylococcus aureus (IGZ = 35 mm). The antiproliferative activity of biohybrids was highlighted by a therapeutic index value of 1.30 for HT-29 cancer cells and 1.77 for HepG2 cancer cells. At concentrations below 102.2 µM, these materials are not hemolytic, so they will not be harmful when found in the bloodstream. In conclusion, hybrid systems based on phyto-Ag/AgClNPs, artificial cell membranes, and chitosan can be considered potential adjuvants in liver and colorectal cancer treatment.

“…However, these physical and chemical methods require multi-step processing and might prove toxic to the environment (Kumari and Singh 2016 ; Jamdagni et al 2018 ; Malik et al 2014 ). Thus, there is a requirement for developing a procedure which will be able to achieve the synthesis of an innovative photo-catalyst in nano-structured form for removal of contamination from waste water (Alishah et al 2016 ; Pattanayak et al 2015 ; Rashidi and Islami 2020 ; Saad et al 2017 ). In recent years, medicinal plant extract-mediated green synthesis of semiconductor-based photocatalyst gained more attention due to their eco-friendly nature and cost effectiveness.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
