“…Formation of zinc nanoparticles in aqueous colloidal solution were confirmed using Ultraviolet-visible spectral analysis. Zinc nanoparticles normally show a broad peak in the UV-vis spectrum in the range of 230-330 nm (Revina et al 2007). The optical transitions have been observed at 327.50 and 330.00 nm (Fig.…”

Nanobiotechnology, the bio-branch of nanotechnology is considered to be one of the fastest emerging research fields. Biosynthesis of metallic nanoparticles is currently under exploitation. Use of plant and plant materials for the synthesis of Zinc nanoparticles is relatively new and exciting research field. The biogenic zinc nanoparticles were synthesized using the leaves of Parthenium hysterophorous by green synthesis route. UV-VIS absorption spectroscopy was used to monitor the quantitative formation of zinc nanoparticles. The characteristics of the synthesized zinc nanoparticles were studied using scanning electron microscopy and nanoparticle analyzer. Zinc nanoparticles were observed to be spherical in shape with size range of 16 to 108.5 nm. The measured zeta potentials varied from 100.4 to 117.20 mV indicate high dispersion of the zinc nanoparticles. The synthesized zinc nanoparticles showed good enzymatic activity and microbial activity. The physiological parameters increased from 30 to 60 days of sowing when compared to control.

“…The spectrum showed the absorbance peak at 240 nm corresponding to the characteristic LSPR band of ZnO nanoparticles. The biomatrix present in the stem bark extract of B. ovalifoliolata may lead to the change in the absorbance UV-Vis micrograph (Gunalan et al 2012;Revina et al 2007). The bioreduction of zincs is extracellular and promises the vast development of green synthesis of metallic nanoparticles using the plants and plant bark sources.…”

Synthesis of metal nanoparticles using biological systems is an expanding research area in nanotechnology. Moreover, search for new nanoscale antimicrobials is been always attractive as they find numerous avenues for application in medicine. Biosynthesis of metallic nanoparticles is cost effective and eco-friendly compared to those of conventional methods of nanoparticles synthesis. Herein, we present the synthesis of zinc oxide nanoparticles using the stem bark extract of Boswellia ovalifoliolata, and evaluation of their antimicrobial efficacy. Stable ZnO nanoparticles were formed by treating 90 ml of 1 mM zinc nitrate aqueous solution with 10 ml of 10 % bark extract. The formation of B. ovalifoliolata barkextract-mediated zinc oxide nanoparticles (BZnNPs) was confirmed by UV-visible spectroscopic analysis and recorded the localized surface plasmon resonance (LSPR) at 230 nm. Fourier transform infrared spectroscopic (FT-IR) analysis revealed that primary and secondary amine groups in combination with the proteins present in the bark extract are responsible for the reduction and stabilization of the BZnNPs. The morphology and crystalline phase of the nanocrystals were determined by Transmission electron microscopy (TEM). The hydrodynamic diameter (20.3 nm) and a positive zeta potential (4.8 mV) were measured using the dynamic light scattering technique. The antimicrobial activity of BZnNPs was evaluated (in vitro) against fungi, Gram-negative, and Gram-positive bacteria using disk diffusion method which were isolated from the scales formed in drinking water PVC pipelines.

“…The biological synthesis of zinc oxide nanoparticles at different durations was confirmed using UV-visible spectral analysis. Characteristic broad peak in the UV-visible spectrum for zinc oxide nanoparticles ranges nano particle from 230-330 nm (Revina et al, 2007). In the present investigation, optical transitions have been observed for all the treatments which range from 332 -346 nm (Table 1).…”
