“…In a single step, aggregated nanoparticles with high crystallinity and aqueous stability were prepared using FeCl 3 .6H 2 O and FeCl 2 .4H 2 O as precursors. Lastovina et al (2017) showed that a two-step microwave heating process can be applied for the synthesis of magnetite and maghemite nanoparticles Fig. 4.…”

The ever-increasing importance of green-based iron nanoparticles within the last decade and their environmental applications is a compelling reason to probe novel routes for their synthesis. Therefore, the principles of green chemistry, waste prevention, energy efficiency, safer solvents, and the benign precursor materials have become fundamental considerations in the synthesis process of these materials, birthing extensive study in this field. In this light, a comprehensive discussion of the successes of greener techniques and other biological nanotechnologies including the use of microorganisms (fungi, bacteria, actinomycetes, and viruses), algae, plant and their extracts for the synthesis of iron (Fe) nanoparticles (NPs) is presented. Although promising findings have been reported, substantial research gaps and the opportunity to capitalize on the emergence and rise of these eco-friendly sources have been identified. The application of synthesized nanoparticles for environmental remediation and their toxicological implications are also discussed.

“…Since the XANES method makes it possible to also investigate the density of unoccupied electronic states above the Fermi level, it is sensitive to the oxidation state of the ion under investigation [ 62 , 63 ]. Thus, on the basis of a comparison of the energy position of the absorption edge in the material under study, with the spectra of reference samples with a known oxidation state of the ion, it is possible to determine the oxidation state of the ion in the material under study [ 64 ]. The position of the inflection point of the absorption edge is determined by the maximum of the first derivative at this point [ 65 , 66 , 67 ].…”

“…Thus, a different chemical shift of the main absorption edge is observed in the XANES spectra for Fe 3 O 4 and γ-Fe 2 O 3 compounds. Comparison of the energy positions of experimental XANES peaks (7185, 7226, and 7275 eV) and their intensities in the spectrum of the synthesized SPIONs with the reference ones made it possible to establish that the synthesized sample has a local atomic structure analogous to the γ-Fe 2 O 3 phase of macroscopic iron oxide [ 64 ]. A similar study of the local atomic structure, carried out in Ref.…”

The Local Atomic Structure of Colloidal Superparamagnetic Iron Oxide Nanoparticles for Theranostics in Oncology

2018

The paper contains an overview of modern spectroscopic methods for studying the local atomic structure of superparamagnetic nanoparticles based on iron oxide (SPIONs), which are an important class of materials promising for theranostics in oncology. Practically important properties of small and ultra small nanoparticles are determined primarily by their shape, size, and features of the local atomic, electronic, and magnetic structures, for the study of which the standard characterization methods developed for macroscopic materials are not optimal. The paper analyzes results of the studies of SPIONs local atomic structure carried out by X-ray absorption spectroscopy at synchrotron radiation sources and Mössbauer spectroscopy during the last decade.

“…Using MW-assisted synthesis in organic solution, Lastovina et al [146] synthesized maghemite NPs via thermal decomposition of Fe(acac) 3 in the presence of oleylamine and 1,2-hexadecanediol and varying amounts of oleic acid. Precursors were irradiated at 120 °C for 60 min in the first step, and at 185 °C for 90 min in the second step.…”

Here, we present a comprehensive review on the use of microwave chemistry for the synthesis of iron-oxide nanoparticles focused on molecular imaging. We provide a brief introduction on molecular imaging, the applications of iron oxide in biomedicine, and traditional methods for the synthesis of these nanoparticles. The review then focuses on the different examples published where the use of microwaves is key for the production of nanoparticles. We study how the different parameters modulate nanoparticle properties, particularly for imaging applications. Finally, we explore principal applications in imaging of microwave-produced iron-oxide nanoparticles.
