Abstract

This study mainly employs magnetic nanoparticles (MNPs) for an amazing variety of engineering and biomedical applications. Herein MNPs are fabricated from fine ferromagnetic particles of iron ferrite by chemical co-precipitation technique, and their average size is about 27 nm via HR-TEM micrograph and XRD analysis to investigate. In this study, MNPs have been demonstrated their excellent properties of heat transfer, electric conductivity, magnetism within the applications for multi-loop pulsating heat pipe (MLPHP), switch-based nanodevice, microfluidic on-chip system and nanogap-based DNA sensor. Based on the effect of magnetic field for MNPs, MLPHP can enhance thermal performance itself at different heating power. In addition, the switch-based nanodevice with MNPs can efficiently add and remove an electrical function of electron charging with current shift. Furthermore, the microfluidic chip utilizing MNPs is demonstrated that can be suited for drug delivThis study mainly employs magnetic nanoparticles (MNPs) for an amazing variety of engineering and biomedical applications.

磁性纳米颗粒在工程和生物医学中的应用

本研究主要采用磁性纳米颗粒(MNPs)用于各种工程和生物医学应用。本文采用化学共沉淀法将铁氧体铁磁微粒制备成MNPs，通过HR-TEM显微照片和XRD分析研究其平均尺寸约为27 nm。在这项研究中，MNPs在多回路脉动热管(MLPHP)、基于开关的纳米器件、微流控片上系统和基于纳米间隙的DNA传感器等方面的应用证明了其优异的传热、导电性和磁性。基于磁场对MNPs的影响，MLPHP可以在不同的加热功率下增强自身的热性能。此外，基于开关的纳米器件可以有效地增加和去除电子随电流移动充电的电学功能。此外，利用磁性纳米颗粒(MNPs)的微流控芯片被证明可以适用于药物输送。这项研究主要利用磁性纳米颗粒(MNPs)在各种工程和生物医学应用中得到惊人的应用。本文采用化学共沉淀法将铁氧体铁磁微粒制备成MNPs，通过HR-TEM显微照片和XRD分析研究其平均尺寸约为27 nm。在这项研究中，MNPs在多回路脉动热管(MLPHP)、基于开关的纳米器件、微流控片上系统和基于纳米间隙的DNA传感器等方面的应用证明了其优异的传热、导电性和磁性。基于磁场对MNPs的影响，MLPHP可以在不同的加热功率下增强自身的热性能。此外，基于开关的纳米器件可以有效地增加和去除电子随电流移动充电的电学功能。此外，利用MNPs的微流控芯片可以适用于药物输送。最后，我们使用MNPs开发了一种检测飞摩尔DNA的电方法，可以为临床基因诊断系统放大低目标DNA浓度。最后，我们使用MNPs开发了一种检测飞摩尔DNA的电方法，可以为临床基因诊断系统放大低目标DNA浓度。
