The external alternating magnetic field generates the propulsion and steering force of the microrobot.
This paper proposes a swimming microrobot driven by an external alternating magnet field using two pairs of Helmholtz coils.
The application of prolonged 1 h external alternating electric fields deteriorated the whole-cell performance in the presence of toxins.
In this work, the influence of an external alternating magnetic field on combustion of a ferrofluid (liquid with dispersed magnetic nanoparticles) droplet is investigated.
Furthermore, many liposomal formulations have been designed to actively release their content in response to specific stimuli, such as a pH decrease, heat, external alternating magnetic field, ultrasound or light.
Under the influence of an external alternating magnetic field, the process of aligning and misaligning repeats itself in each cycle, producing heat by viscous dissipation, due to a periodically reversing nanoparticle circular motion.
Herein, we developed doxorubicin-loaded magnetic PLGA microspheres (DOX-MMS), in which DOX was encapsulated in the core and high contents (28.3 wt%) of γ-Fe2O3 nanoparticles (IOs) were electrostatically assembled on the surface of microsphere to ensure the high sensitivity to response of an external alternating current magnetic field (ACMF).
Moreover, the impacts could be more effectively reduced by superimposition of the external alternating magnetic field which may exert effects not only on demagnetization of the diamond grains, but also on cations' deposition process since the external magnetic field is much stronger than that produced by diamond.
Here we show that applying an external alternating magnetic field (AMF) to an LM induces various physical phenomena, such as exothermic behavior, controlled locomotion, electromagnetic levitation, and transformations of the LMs between different morphologies and configurations, in a non-contact manner.
After FMNP-labeled MSCs arrived in local tumor tissues, subcutaneous tumor tissues in nude mice were treated under external alternating magnetic field.
