Synthesis, characterization and evaluation of effect of phytogenic zinc nanoparticles on soil exo-enzymes

Abstract

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.

Green Synthesis of Zinc Oxide Nanoparticles Using Parthenium hysterophorus Leaf Extract and Evaluation of their Antibacterial Properties

“…FTIR analysis of the ZnONP reveals the appearance of bonds that confirms the presence of certain enzymes that are responsible for the reduction, capping and stability of the nanoparticles. It can be stated that the nanoparticles are shielded by the enzymes and the proteins present in the extract so as to help prevent the formation of clusters ( Figure 3) [8].…”

“…Furthermore, large quantities of secondary waste are generated resulting from the addition of chemical agents for precipitation and reduction in the processes [7]. Because of these shortcomings, biosynthetic methods employing either microorganisms or plant extracts are rapidly emerging as a simple alternative for nanoparticle synthesis [8]. Due to their amenability to biological functionalization; the naturally synthesized nanoparticles are finding important applications in the field of medicine.…”

Nanotoxicology of Metal Oxide Nanoparticles

“…ZnO2 nanoparticles were employed as antimicrobial agents and were incorporated into materials such as textiles and personal care items [114]. Green synthesized zinc nanoparticles (size 16-108 nm), using leaves of Parthenium hysterophorous, demonstrated enzymatic and microbial activity [115]. The physiological parameters, which were related to the growth of Arachis hypogea L. pot culture, increased from 30 to 60 days of sowing compared with the control group.…”

“…The physiological parameters, which were related to the growth of Arachis hypogea L. pot culture, increased from 30 to 60 days of sowing compared with the control group. Therefore, biogenic ZnO nanoparticles with microbial activity may have applications in agriculture, where zinc is one of the essential micronutrients that need to be supplied to the crop [115].…”

Electrochemical fabrication of Ag–Cu nano alloy and its characterization: an investigation

“…In particular, it has enthralled much attention in the field of medicine [22,23] due to their excellent bactericidal eminence. For many years, materials containing particles of metals and their alloys such as copper [24,25], gold [26], silver [27,28], titanium [28] and zinc [27,29] have been extensively used for antimicrobial applications due to their ability to penetrate through the microorganism causing cell deformation and it has been established that the bactericidal intensity increases with decrease in particle size. In particular, the silver-copper alloy was extensively used for its antibacterial and antiseptic applications in the field of medicine and drug delivery [30,31].…”
