Eco-friendly green synthesis of silver nanoparticles from Aegle marmelos leaf extract and their antimicrobial, antioxidant, anticancer and photocatalytic degradation activity

Biosynthesis, characterization, and investigation of antimicrobial and cytotoxic activities of silver nanoparticles using Solanum tuberosum peel aqueous extract

“…Ag NPs produce Ag + in mitochondria and nucleus, causing cell damage and apoptosis. Ag NPs were reported to have minimal toxicity in healthy human cells [ [43] , [44] , [45] ]. The cytotoxic effects of the Ag NPs produced from S. tuberosum peel extracts were evaluated on the Skov-3, Caco-2, U118, and HDF cell lines at various concentrations, which can be seen in Fig.…”

Green Synthesis of Silver Nanoparticles Using Jasminum nudiflorum Flower Extract and Their Antifungal and Antioxidant Activity

“…Notably, the substantial absorption peaks observed at 1029 cm −1 , 2922 cm −1 , and 3414 cm −1 primarily correspond to the polyphenols extracted from the plants [ 28 ]. Additionally, peaks at 3795 cm −1 , 3452 cm −1 , 3439 cm −1 , 3430 cm −1 ,3422 cm −1 , 3418 cm −1 , 3360 cm −1 , and 3255 cm −1 can be ascribed to the stretching vibrations of the O-H or N-H groups present in alcohol or phenol compounds that bind to the surface of AgNPs [ 44 , 45 , 46 , 47 , 48 ].…”

“…Moreover, peaks at 2930 cm −1 , 2923 cm −1 , 2922 cm −1 ,2921 cm −1 , 2900 cm −1 , and 2880 cm −1 are associated with the C-H stretching vibrations of alkanes [ 23 , 28 , 35 , 46 , 47 ]. The presence of aldehyde or ketone functional groups (C=O) from flavonoid and tannin derivatives can be inferred from the peaks at 1617 cm −1 ,1626 cm −1 , 1650 cm −1 , and 1653 cm −1 [ 44 , 47 , 49 ].…”

While the peak at 1633 cm −1 and 1631 cm −1 signifies C=C stretching vibrations of the hydrocarbon portion of biological double-bond molecules, the band at 1052 cm −1 and 1031 cm −1 may be attributed to C-O stretching [ 35 , 46 , 50 ].…”
