Abstract

Doped magnetic nanoparticles (DMNPs) have become a fascinating class of nanomaterials with important implications in science and technology. The comprehensive review focuses on the synthetic methods, types of doping elements, distinctive properties, and extensive applications of DMNPs. The synthesis section highlights different methods, highlighting their benefits and drawbacks, such as chemical precipitation, co-precipitation, thermal breakdown, sol-gel, and other processes. Strategies for increasing the stability and functioning of DMNP are also reviewed, including surface functionalization and ligand exchange. An in-depth study is done to clarify how doping materials including transition metals, non-metals, and rare earth elements affect the chemical stability and magnetic characteristics of DMNP. Applications in various fields, such as biomedicine (MRI contrast agents, medication transport, antibacterial activity), environmental remediation (water purification, heavy metal removal), and sensing technologies, heavily rely on these features. DMNPs offer much potential in a variety of disciplines. Still, there are several challenges to their adoption, including regulatory and safety concerns, cost-effectiveness issues, and scalability issues. More research is required to overcome these difficulties and maximize the use of MDNPs for ensuring food safety.
掺杂磁性纳米颗粒:从合成到应用技术前沿
掺杂磁性纳米颗粒(DMNPs)已成为一类引人注目的纳米材料,具有重要的科学和技术意义。综述了DMNPs的合成方法、掺杂元素类型、性能特点及广泛应用。合成部分重点介绍了不同的方法,突出了它们的优缺点,如化学沉淀法、共沉淀法、热击穿法、溶胶-凝胶法等。综述了提高DMNP稳定性和功能的策略,包括表面功能化和配体交换。深入研究了过渡金属、非金属、稀土等掺杂材料对DMNP化学稳定性和磁性的影响。生物医学(MRI造影剂、药物转运、抗菌活性)、环境修复(水净化、重金属去除)和传感技术等各个领域的应用都严重依赖于这些特性。DMNPs在各种学科中提供了很大的潜力。尽管如此,它们的采用仍面临着一些挑战,包括监管和安全问题、成本效益问题和可扩展性问题。需要进行更多的研究来克服这些困难,并最大限度地利用mndps来确保食品安全。

期刊介绍: Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields. Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication. The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
