Magnetic-Field-Induced Locomotion of Glass Fibers on Water Surfaces: Towards the Understanding of How Much Force One Magnetic Nanoparticle Can Deliver

The amount of force one magnetic nanoparticle (MNP) can deliver is calculated using Fe3O4 MNPs building blocks to modify glass fibers. Our results demonstrate that one weight unit of Fe3O4 MNPs can eventually drag approximate to 10000 times its own weight on a water surface, a significant finding for the development of new magnetic delivery systems and micromanipulators.
