Abstract

Magnetic nanoparticles (MNPs), particularly iron oxide nanoparticles (IONPs), play a pivotal role in biomedical applications ranging from magnetic resonance imaging (MRI) enhancement and cancer hyperthermia treatments to biosensing. This study focuses on the synthesis, characterization, and application of IONPs with two different size distributions for frequency mixing magnetic detection (FMMD), a technique that leverages the nonlinear magnetization properties of MNPs for sensitive biosensing. IONPs are synthesized through thermal decomposition and subsequent growth steps. Our findings highlight the critical influence of IONP size on the FMMD signal, demonstrating that larger particles contribute dominantly to the FMMD signal. This research advances our understanding of IONP behavior, underscoring the importance of size in their application in advanced diagnostic tools.

摘要

磁性纳米颗粒（MNPs），尤其是氧化铁纳米颗粒（IONPs），在从磁共振成像（MRI）增强、癌症热疗到生物传感等一系列生物医学应用中发挥着关键作用。本研究聚焦于具有两种不同尺寸分布的IONPs的合成、表征及其在频率混合磁检测（FMMD）中的应用，FMMD是一种利用MNPs的非线性磁化特性进行灵敏生物传感的技术。IONPs通过热分解及后续生长步骤合成。我们的研究结果突出了IONP尺寸对FMMD信号的关键影响，表明较大颗粒对FMMD信号的贡献占主导。这项研究增进了我们对IONP行为的理解，强调了尺寸在其应用于先进诊断工具中的重要性。
