Special Issue Information
Dear Colleagues,
In recent decades, magnetic materials have received increasing attention due to their applications in specialized fields, including catalysis, biomedicine, environmental remediation, and energy conversion and storage. To date, numerous magnetic materials, including elementary nickel, cobalt, CoPt alloy, metal ferrite, etc., have been screened with many applications such as semiconductors and photovoltaics. For example, pristine magnetite has been demonstrated to have peroxidase activity, which can be used to promote the decomposition of H2O2, showing promising prospects in environmental treatment. In addition, the immobilization of noble nanoparticles or enzymes onto magnetic supports enables the ease of recovery of these catalytically active species, simplifying the catalytic process. Furthermore, coating a thin layer of functional materials on the surface of magnetic materials improves the acid resistance of magnetic materials and expands their application area, such as magnetic adsorbent, magnetic drug support, and so on. Significantly, a series of sensors for virus detection are achieved by surface modifying magnetic materials with biomolecules, such as antibodies, oligonucleotides, and aptamers, which are capable of selective binding with target viruses or their biomarkers in biological samples.
Despite these achievements in the area of magnetic materials, challenges still exist in both developing new magnetic materials and expanding their applications. Precise control of finite size, uniformity, and surface effects is of paramount significance in biomedical application to unveil the correlation between their structural features and properties of magnetic materials obtain desired application performance. Furthermore, the family of magnetic materials should be enlarged since current available magnetic materials are limited. In particular, multicomponent magnetic nanostructures are expected to be the next generation of advanced magnets to offer enhanced magnetic, optical, or catalytic properties. Additionally, more calculation models are urgently needed to reveal the support effect in catalysis application. Thanks to nonstop efforts from various research fields, it is out of the question that magnetic materials will bring us a prospective future in many fields.
Taking these goals in mind, this Special Issue will focus on new ideas in presenting recent progress in studies related to magnetic materials, covering a wide range of topics. Both original research and review articles are welcome for this Special Issue. Areas of interest include but are not limited to:
- Synthesis of magnetic materials
- Characterization techniques of magnetic materials
- Calculation models for designing magnetic materials
- Magnetic-material-based catalysts
- Magnetic-material-based sensors
- Magnetic solid-phase extraction of pollutants from water
- Advanced bioimaging techniques based on magnetic materials
- Magnetic material based drug carrier
