Green Synthesis of Silver Nanoparticles using Mediterranean Cypress (<i>Cupressus sempervirens</i>) Leaf Extract

Abstract

Silver nanoparticles (AgNPs) retained vast applications in science and technology. Due to the vast application of these particles in various disciplines, there is an interest for synthesis of AgNPs in an environmentally friendly and economic manner. For the first time we were used Mediterranean cypress (Cupressus sempervirens) leaf aqueous extract for biosynthesis of AgNPs. Prepared particles were in various shapes and their diameters were ranging from 10 to 80 nm. TEM micrographs were shown that AgNPs are capped with a biologic matrix. FTIR analysis indicates hydrophilic functional groups in the capping matrix which can improve the stability of AgNPs.

“…Based on the TEM micrographs, INPs were heavily surrounded by biological components from leaf extract ( Figure S1), therefore, the resulting structure is a microstructure which composed of INPs and phytochemical compounds. Similar phenomenon is reported for the green synthesis of metal nanoparticles using a variety of plant extracts [16,23,49,50]. In some cases it has been confirmed that this biologic matrix is mainly composed of carbohydrates from leaf extract [23,49].…”

Silver Nanoparticles: Mechanism of Action and Probable Bio-Application

“…Flavonoids are particularly interesting in this case due to their high antioxidant activity for medical purposes. Hydrophilic functional groups of various compounds surrounding nanoparticles make them colloid-stable in an aqueous medium [ 88 ]. Other interesting substances that act as reducing and stabilizing substances are the sucrose and fructose of garlic extract [ 89 ].…”

“…Plant extracts are now vastly studied and used for the green synthesis of various nanostructures. The potential of extracts from different parts of plants such as leaf, fruit, flower, and seed is examined for the green synthesis of nanoparticles [3,[14][15][16][17][18][19]. In addition to plant extract, living plants have also the potential to perform green synthesis of nanoparticles, which means that some living plants are able to synthesize and maintain nanoparticles in their tissue.…”
