“…It was investigated how the initial concentration of heavy metals affected the effectiveness of adsorption. The adsorbents were mixed with an aqueous solution at concentrations of (1.0, 2.0, 3.0, 5.0, and 10) mg/L with the same 45 min contact time and dose of 0.4 g. The experiment used 1 L of a synthetic aqueous solution rotating at 150 rpm [ 17 ].…”

“…The effect of pH on the adsorption of Cu, Pb, Se, Zn, and Cr ions in the solution has been established and considered an important parameter affecting the performance of the adsorption process. At varied pH levels (3,6, and 9), removing of Cu, Pb, Se, Zn, and Cr ions from the aqueous solution was conducted with a constant dosage of 0.4 g/L at 150 rpm/45 min [ 17 ].…”

“…Different applications of magnetic nanoparticles exist, such as cancer diagnosis, drug delivery vehicles, and water remediation [ 15 , 16 ]. Iron nanoparticles (Fe-NPs) can be created using a variety of techniques, including hydrothermal precipitation, sol-gel, emulsion, mono-chemical processing, precipitation, and thermal plasma arc processes [ 17 ]. The Fe-NPs produced by physical and chemical processes are complicated, outdated, expensive, and produce hazardous toxic waste that is harmful to the environment as well as human health [ 18 ].…”

The iron nanoparticles (Fe-NPs) have been synthesized using an environmentally friendly and simple green synthesis method. This study aims to obtain an aqueous extract from natural material wastes for synthesizing Fe-NPs. The produced Fe-NPs were evaluated as adsorbents for removing Pb, Se, Cu, Zn, and Cr from aqueous solutions. The formation of Fe-NPs was observed on exposure of the aqueous extract to the ferrous chloride and ferric chloride solutions. The characterization of the synthesized Fe-NPs was carried out using different instrumental techniques. As a function of the initial metal ion concentration, contact time, and various doses, the removal of the heavy metal ions was investigated. The UV-Vis spectrum of Fe-NPs showed a peak at 386 nm, 386 nm, 400 nm, 420 nm, 210 nm, 215 nm, and 272 nm of banana, pomegranate, opuntia, orange, potato, and onion, respectively. The FT-IR spectra confirmed the attachment of bioactive molecules from plants on the Fe-NPs surface. The effective reduction of metal ions was greatly aided by the -OH functional groups. The functional groups were examined and responsible for adsorption process by nanoparticle powder sample, these peaks are 3400 cm−1, 2900 cm-1, 1600 cm−1,1000 cm−1, and 1550 cm−1. The magnetization measurements revealed superparamagnetic behavior in the produced iron oxide nanoparticles. Heavy metal ions uptake followed a time, dose, and initial concentration-dependent profile, with maximum removal efficiency at 45 min, 0.4 g, and 3.0 mg/L of metal concentration, respectively.

“…Aspergillus flavus has been used for the extracellular synthesis of spherical IONPs with an average size of 28–33 nm. Different functional groups such as alkyl, carboxylic acid, hydroxyl, and amide were responsible for the reduction and capping of Aspergillus flavus mediated IONPs [ 45 ]. Baskar et al (2017) synthesized IONPs ranging in size from 40–100 nm using Aspergillus terreus.…”

Nanotechnology is a booming avenue in science and has a multitude of applications in health, agriculture, and industry. It exploits materials’ size at nanoscale (1–100 nm) known as nanoparticles (NPs). These nanoscale constituents are made via chemical, physical, and biological methods; however, the biological approach offers multiple benefits over the other counterparts. This method utilizes various biological resources for synthesis (microbes, plants, and others), which act as a reducing and capping agent. Among these sources, microbes provide an excellent platform for synthesis and have been recently exploited in the synthesis of various metallic NPs, in particular iron. Owing to their biocompatible nature, superparamagnetic properties, small size efficient, permeability, and absorption, they have become an integral part of biomedical research. This review focuses on microbial synthesis of iron oxide nanoparticles using various species of bacteria, fungi, and yeast. Possible applications and challenges that need to be addressed have also been discussed in the review; in particular, their antimicrobial and anticancer potentials are discussed in detail along with possible mechanisms. Moreover, some other possible biomedical applications are also highlighted. Although iron oxide nanoparticles have revolutionized biomedical research, issues such as cytotoxicity and biodegradability are still a major bottleneck in the commercialization of these nanoparticle-based products. Addressing these issues should be the topmost priority so that the biomedical industry can reap maximum benefit from iron oxide nanoparticle-based products.
