The principal constraint in the application of the microrobots in drug delivery is swarm control. The rotating magnetic field has shown the potential of capturing and controlling the swarm of magnetic nanoparticle-based microrobots. Despite various experimental studies to capture the swarm of the magnetic nanoparticle-based microrobot in a rotating magnetic field, a simulation platform for the swarm of aggregated magnetic nanoparticles (MNPs) has not been introduced. This study proposes a simulation platform to study the swarm of aggregated magnetic nanoparticles in a rotating field. An experimental setup was developed to investigate the different swarm modes in a rotating magnetic field, and the results show an agreement between the experimental and simulation results for the micro- and nanoparticles. The effects of the environmental parameters (initial dispersion of nanoparticles), process parameters (magnetic field intensity, frequency, actuation time), and geometrical parameters (particle diameter) were studied to describe the swarm behavior in a rotating magnetic field. These studies revealed the role of each parameter in creating the swarm and showed how the size of aggregates can be controlled. The presented approach can be used to design the magnetic nanoparticle-based microrobots effectively.

旋转磁场下MNPs不同群模式的研究

微型机器人在药物输送中的应用的主要限制是群体控制。旋转磁场已显示出捕获和控制基于磁性纳米粒子的微型机器人群的潜力。尽管进行了各种实验研究以在旋转磁场中捕获基于磁性纳米粒子的微型机器人群,但尚未引入用于聚集磁性纳米粒子 (MNP) 群的模拟平台。本研究提出了一个模拟平台来研究旋转场中聚集的磁性纳米粒子群。开发了一个实验装置来研究旋转磁场中的不同群模式,结果表明微米和纳米粒子的实验和模拟结果之间存在一致性。研究了环境参数(纳米粒子的初始分散)、工艺参数(磁场强度、频率、驱动时间)和几何参数(粒径)的影响,以描述旋转磁场中的群体行为。这些研究揭示了每个参数在创建群体中的作用,并展示了如何控制聚集体的大小。所提出的方法可用于有效地设计基于磁性纳米粒子的微型机器人。这些研究揭示了每个参数在创建群体中的作用,并展示了如何控制聚集体的大小。所提出的方法可用于有效地设计基于磁性纳米粒子的微型机器人。这些研究揭示了每个参数在创建群体中的作用,并展示了如何控制聚集体的大小。所提出的方法可用于有效地设计基于磁性纳米粒子的微型机器人。
