Effect of bulk and nano-Fe 2 O 3 particles on peanut plant leaves studied by Fourier transform infrared spectral studies

Green synthesis of iron oxide nanoparticle using Carica papaya leaf extract: application for photocatalytic degradation of remazol yellow RR dye and antibacterial activity

“…The intense and sharp peaks undoubtedly revealed that Fe 2 O 3 nanoparticles formed by the reduction method using Carica papaya leaf extract were crystalline in nature. The results are almost similar to the results obtained for iron oxide nanoparticles by other researchers ( Ahmmad et al., 2013 ; Suresh et al., 2016 ; Lassoued et al., 2018 ). The average crystallite size as determined using the Debye–Scherrer equation was found to be 4.58 nm.…”

Synthesis and characterization of ZnO phytonanocomposite using Strychnos nux-vomica L. (Loganiaceae) and antimicrobial activity against multidrug-resistant bacterial strains from diabetic foot ulcer

“…Stretching vibrations of 1068.56 cm −1 and 1026.13 cm −1 represented C—O stretching of alcohols and carboxylic acid groups. The above data indicated the presence of phenols, terpenoids, flavonoids, amino acids, carbohydrates, tannins, and saponins in S. nux-vomica plant extract [32] . FTIR spectra of ZnO phytonanocomposite from 40 mL of S. nux-vomica plant extract ( Fig.…”

Carvacrol and linalool co-loaded in β-cyclodextrin-grafted chitosan nanoparticles as sustainable biopesticide aiming pest control

“…Although the plant as a whole can be analyzed to identify possible toxic effects caused by nanoparticles, the leaves are an especially sensitive part of the plant that can provide indications of toxicity by means of symptoms such as chlorosis 61 , 62 . In the present case, it was notable that the nanoparticles did not present phytotoxicity, since no decreases were observed for the photosynthetic pigments, which would be indicative of chlorosis.…”
