Novel biogenic silver nanoparticles as invigorated catalytic and antibacterial tool: A cleaner approach towards environmental remediation and combating bacterial invasion

Influence of the capping of biogenic silver nanoparticles on their toxicity and mechanism of action towards Sclerotinia sclerotiorum

“…3 ). A broad band at 3700−3000 cm − 1 could be attributed to O–H stretching vibrations of hydroxyl groups [ 46 , 47 ]. A band at 2960 cm − 1 was due to stretching of the amide NH groups [ 46 ] in the structures of proteins and hydrolytic enzymes such as glucanases and chitinases.…”

“…A band at 2960 cm − 1 was due to stretching of the amide NH groups [ 46 ] in the structures of proteins and hydrolytic enzymes such as glucanases and chitinases. Bands at 2917 and 2850 cm − 1 were characteristic of C–H stretching [ 8 , 48 ], while bands at 1637 and 1535 cm − 1 could be attributed to amides I and II, respectively [ 38 , 47 ]. An intense band at 1371 cm − 1 was attributed to bending vibration of C–H of methyl groups [ 46 , 49 ] and/or stretching of C–N of aromatic amines [ 8 , 38 , 47 ].…”

Fabrication of CS/GA/RGO/Pd composite hydrogels for highly efficient catalytic reduction of organic pollutants

“…5,6 Precious metal nanoparticles have special optical, catalytic, electrochemical and mechanical properties, so they have potential applications in optics, [7][8][9] catalysis, [10][11][12] microelectronics, [13][14][15] biomedicine 16,17 and many other elds. The most common used catalysts are gold, 18-20 silver 1, [21][22][23][24] and palladium. [25][26][27] In this work, palladium nanoparticles (Pd NPs) were used to catalyze the reaction of 4-NP and 2-NA with sodium borohydride (NaBH 4 ).…”
