Bio-Fabrication of zinc oxide nanoparticles using leaf extract of Parthenium hysterophorus L. and its size-dependent antifungal activity against plant fungal pathogens

Preparation and <i>in-vitro</i> cytotoxicity of zinc oxide nanoparticles against osteoarthritic chondrocytes

“…The reaction between Piper betle plant leaf extract and ZnNO 3 .6H 2 O caused a change in the solution from colorless to pale white within 1 h, and the reaction was complete within 4 h at 80 °C, which was faster and cooler than observed in previous studies [8][9][10]. No color change was observed after 3 days in the control experiment, indicating the importance of Piper betle extract in ZnO NP synthesis.…”

Green synthesis of zinc oxide nanoparticles using Azadirachta indica A. Juss. leaves extract and its antibacterial activity against Xanthomonas orzyae pv. oryzae

“…The role of the neem leaf extract as a reducing and capping agent and presence of some functional groups was confirmed by FTIR analysis of zinc oxide nanoparticle. The representative spectrum of zinc oxide nanoparticles is shown in Figure 8 which suggest zinc oxide absorption band in the region 400 and 600 cm -1 (Sangeetha et al, 2011;Vani et al, 2011;Rajiv et al, 2013). The broad absorbance at 3412 cm -1 is attributed to the O-H stretching modes of vibration in hydroxyl functional group in alcohols and phenolic compounds.…”

“…The broad absorbance at 3412 cm -1 is attributed to the O-H stretching modes of vibration in hydroxyl functional group in alcohols and phenolic compounds. The band 1506 cm -1 corresponds to N-H stretching vibrations in amide-II; 1382 cm -1 represents monosubstituted alkynes (Vani et al, 2011;Rajiv et al, 2013). The observed peak at 1116.72 cm -1 denote -C-OC-linkages, or -C-O-bonds (Ahmed et al, 2015).…”

Biosynthesis and Characterization of Zinc Oxide Nanoparticle Using Ficus Religiosa Leaves Extract

“…[1][2][3] In the biological method, plant extracts are used for controlled and precise synthesis of several metallic nanoparticles. [2] High surface and a large fraction of surface atoms are responsible for the nanoparticles' atom-like behavior.…”

“…[1][2][3] In the biological method, plant extracts are used for controlled and precise synthesis of several metallic nanoparticles. [2] High surface and a large fraction of surface atoms are responsible for the nanoparticles' atom-like behavior. [4,5] Despite the fact that conventional methods use less time for synthesizing nanoparticles, they contribute to environmental toxicity because they require toxic chemicals as capping agents.…”
