Green synthesis derived Pt-nanoparticles using Xanthium strumarium leaf extract and their biological studies

Biofabricated platinum nanoparticles: therapeutic evaluation as a potential nanodrug against breast cancer cells and drug-resistant bacteria

“…66 The Xanthium strumarium leaf extract based platinum nanoparticles reported earlier showed antibacterial activity with the maximum zone of inhibition against E. coli (20 AE 0.5 mm), K. pneumonia (19 AE 0.5 mm), P. aeruginosa (18 AE 0.5 mm), S. aureus (22 AE 0.5 mm), and B. subtilis (19 AE 0.5 mm) at the concentration of 100 mg per well. 29 While Taraxacum laevigatum extract-based platinum nanoparticles reported antibacterial activity against two bacterial species B. subtilis and P. Aeruginosa, the zone of inhibition of Pt-NPs againstB. subtilis was (18 AE 0.8) mm and P. aeruginosa was (15 AE 0.5) mm.…”

“…28 Pt NPs using the leaf extract of X. strumarium havealso been reported to have excellent anti-bacterial activity against a panel of strains. 29 Various methods developed for the synthesis of nanoparticles include physical and chemical methods. Physical methods such as laser ablation, vapor deposition, arc discharge, sputter deposition, ball milling and ame pyrolysis dissipates radiation and consumes enormous energy.…”

Green synthesis of copper nanoparticles using Celastrus paniculatus Willd. leaf extract and their photocatalytic and antifungal properties

“…Recently, biosynthesized nanoparticles (NPs) attracted much attention due to their photocatalytic application in the degradation of organic dyes [ 6 ]. Different types of plants and their derived products have been used successfully in the synthesis of different green nanoparticles of zinc oxide [ 7 , 8 ], platinum [ 9 ], palladium [ 10 ], silver [ 11 , 12 ], cobalt [ 13 ], magnetic [ 14 ], and gold [ 15 ].…”

Green Synthesis of Transition-Metal Nanoparticles and Their Oxides: A Review

“…The extract solution was then introduced into 190 mL of 1 mM aqueous H 2 PtCl 6 ·6H 2 O to complete a volume of 200 mL. The reaction temperature was then increased to 100 °C and left for 1 h. The SEM and TEM images showed that the nanostructures possessed a smooth surface, good alignment and were free from distortion, with cubic to rectangular shapes and an average size of 20 nm [ 122 ].…”

“…Additionally, platinum nanostructures possess the smallest average diameters between the transition-metals examined in this review, with approximately 21 nm ( Table S14 ). The majority of the nanoparticles retained spherical shapes, however; some studies produced rod-like, wire-like, dodecahedron, hexagonal, and rectangular morphologies [ 122 , 126 , 127 , 128 , 129 ].…”
