Abstract
To synthesized and
characterized green iron nanoparticles extracted from plants. Synthesis of iron
bio-nanoparticles was done by using ALoe vera gel water extract as
un-reducing agent. Characterization of Iron nanoparticles was performed using
UV, XRD, and FTIR. The diameter of iron nanoparticles was about 52 nm.
The effect of the exposure of Aloe vera seeds to iron
nanoparticles on germination of Lepidium sativum has been studied.
Seeds were exposed to green iron nanoparticles. Germination percentage and root
shoot length were calculated. The results showed a reduction in germination
percentage on exposure to 1000ppm of green nanoparticles while maximum
germination percentage was on application of iron nanoparticles at 500ppm. Root
and shoot growth was enhanced under iron nanoparticles application while
reduction in root and shoot length was observed on exposure to 1000ppm of
nanoparticles and Fe.

Introduction
Synthesis Green iron
nanoparticles, instead of using chemical reducing agent such as sodium
borohydride which is flammable and corrosive (Khenfouch et al., 2016). Now a
day’s researcher used extracts of plant part in preparing nano particles
(Nyangiwe et al., 2015).
These tiny products
also have a large surface area to volume ratio, which is their most important
feature responsible for the widespread use of nanomaterials in mechanics,
optics, electronics, biotechnology, microbiology, environmental remediation,
medicine, numerous engineering fields and material science (Sone et al., 2017).
Different protocols have been designed for the production of metallic
nanoparticles. Chemical physical, electrical and Biological (Sundus et al.,
2013).
The coating is used to
stabilize the particles in colloidal form, to prevent them from degradation and
to minimize the toxicity. Generally, magnetite and maghemite are the two
important forms of iron oxide, which are used as the magnetic materials for
biomedical applications (Sundus et al., 2017).
Agglomeration of
magnetic nanoparticles is inevitable, because of their Vander Waals attractive
forces between the tiny particles. Magnetite (Fe3O4) nanoparticles are
chemically stable and non carcinogenic and has high saturation value (92emu/g)
compared to the maghemite bulk material.
The production of iron
nanomaterials, such as metallic iron and oxide of iron via a more convenient
greener route, is a great step forward in the development of nanomaterials.
This review highlights the significance of biogenic approaches and the role of
biocompatible green materials in technological and economically feasible
process and practices (Sundus 2018).
The main objective of
the current study is to preparation green iron nano particles by using Aloe
vera gel and characterize it by absorption spectrophotometer (UV- VIS), X-ray
diffraction (XRD), and scanning electron microscope (FTIR).
Studying Several
indexes during the germination seed of Lepidium sativum such as root length,
shoot length, fresh weight and germination ratio. To the best of our knowledge,
it is the first reports focused on the effect of Lepidium sativum seeds
germinating after exposing to Aloe vera iron nano particles nanoparitcles with
different morphologies.
