Special Issue Information

Dear Colleagues,

Magnetic nanomaterials are widely studied today, in both theoretical and applied research, due to their high applicability potential in nanotechnology and nanomedicine. Due to their small size, in the accepted range of 1-100 nm, their shape and embedding/dispersion in different media (solids, liquids, gases/powders, biological media), magnetic nanomaterials of different types (nanoparticles, nanocomposites, nanopowders, and other nanostructures) change their properties and their magnetic structure compared to bulk material, which gives them a wide versatility for multiple applications in the field of nanotechnology. Additionally, due to their small toxicity and easy handling with external magnetic fields, and the possibility of tailoring their biocompatibility by the use of various techniques in modern nanobiotechnology (bioencapsulation, biosurfactation, biofunctionalization, bioconjugation, coating with various biocompatible organic chemical agents, etc.), magnetic nanomaterials have found multiple applications in modern nanomedicine, for diagnostics, therapy or as nanotheranostic tools such as MRI, drug delivery, MHT in cancer therapy etc.

Having in view the current research of high interest in the field of magnetic nanomaterials, this Special Issue is dedicated to publishing current results in the form of original research articles, as well as summarizing current results in concise reviews.

It can be observed that magnetic iron-oxide nanoparticles are increasingly used in bioassay methods. This is due to their stability in aqueous solutions, ease of functionalization, biocompatibility and very low toxicity. Here, we show that the recent discovery of the ability of magnetic nanoparticles to self-assemble into 2D structures of ordered chains may be exploited for bioassays. This would open up the possibility of controlled immobilization of proteins, enzymes, DNA or RNA and other molecular systems on spatially ordered nanostructures. In this work, fluorescein was used as an example. Also shown is the possibility of using Raman spectroscopy to analyze material accumulated on such structures. The observed formation of regularly spaced chains of magnetic nanoparticles takes place during the drying process of a thin layer of magnetic liquid placed on an appropriately prepared low-density polyethylene (LDPE) film.

This study aims to evaluate the dependence of DNA damage on the proportion of iron and gold in iron-gold nanoparticle heterojunctions using Monte Carlo simulations. The simulation setup included a spherical nanoparticle with varying percentages of iron and gold, irradiated by photon beams of different energies (50–150 keV). The Geant4-DNA Monte Carlo code was utilized for the accurate tracking of radiation transport. The results reveal that DNA damage increases with a higher percentage of gold volume in the heterojunction, primarily due to photoelectric enhancement. Furthermore, a lower photon beam energy of 50 keV induces greater DNA damage compared to energies of 100 keV and 150 keV. The findings suggest that for effective cancer cell eradication through DNA damage, the gold volume should be equal to or greater than 50% in the iron-gold nanoparticle heterojunction. In conclusion, the findings from this study will shed light on the potential of iron-gold nanoparticle heterojunctions in enhancing radiotherapy outcomes. The investigation of DNA damage resulting from the combination of contrast agents and radiosensitizers is crucial for advancing cancer research and treatment. The knowledge gained from this research will aid in the development of personalized and effective radiotherapy approaches, ultimately improving patient outcomes in cancer treatment. Full article

In recent years, the use of magnetic nanoparticles (MNPs) in biomedical applications has gained more and more attention. Their unusual properties make them ideal candidates for the advancement of diagnosis, therapy, and imaging applications. This review addresses the use of MNPs in the field of biomedicine encompassing their synthesis, biofunctionalization, and unique physicochemical properties that make them ideal candidates for such applications. The synthesis of magnetic nanoparticles involves a range of techniques that allow for control over particle size, shape, and surface modifications. The most commonly used synthesis techniques that play a crucial role in tailoring the magnetic properties of nanoparticles are summarized in this review. Nevertheless, the main characterization techniques that can be employed after a successful synthesis procedure are also included together with a short description of their biomedical applications. As the field of magnetic nanoparticles in biomedical applications is rapidly evolving, this review aims to serve as a valuable resource, especially for young researchers and medical professionals, offering basic but very useful insights into recent advancements and future prospects in this highly interdisciplinary research topic.
