Special Issue Information

Dear Colleagues,

In recent years, significant attention has been paid to advancements in functional magnetic materials (FMMs) and their applications. Magnetic materials designed on a molecular or structural scale exhibit excellent functions and are widely utilized in information technology, sensing, transportation and energy sectors. However, the principals of the mechanisms implicated in the design of FMMs must be fully exploited and utilized in order to obtain enhanced functions and applications.

This Special Issue welcomes roadmap articles focusing on functional magnetic materials technology and addressing the latest developments, current state-of-the-art methods, challenges, and future perspectives in this field.

In this article, we investigated the influence of molecular weight (Mw) on particle deposition efficiency after PEG-functionalized (polyethylene glycol-PEG) magnetoresponsive magnetic cluster targeting. In this work, the clusters were obtained by the solvothermal polyol method using polyethylene glycol (PEG) as a coating agent. So, we investigated three kinds of magnetoresponsive clusters: MNC-2000, MNC-6000, and MNC-10,000. These clusters were coated with PEG, and had molecular weights (Mw) of 2000 Da, 6000 Da, and 10,000 Da, respectively. The authors propose that the key to achieving maximum efficiency in targeted drug delivery is to deposit a thin, uniform layer of medication that covers the vascular wall in the area of interest. We defined a set of efficiency criteria to focus on the most essential characteristics of the targeting results. These are the obstruction degree, which measures the level of vessel obstruction; the magnet coverage degree, which evaluates the quality of particle deposition along the vessel wall; and the proximal deposition degree, which assesses the effect of pulsatile flow on deposition length. We performed several tests to determine how molecular weight affected these efficiency parameters. These tests examined (a) the effect of the injected cluster quantities, (b) the effect of the magnet distance, and (c) the effect of the injection period. Our findings indicate that an increase in PEG’s molar weight significantly impacts magnetic particle targeting efficiency. Full article
