A Tunable Magnetic Trap Platform for Single Particle Manipulation

Abstract

In this Short Term Innovative Research (STIR) project, the physics of magnetic traps originating from domain walls in ferromagnetic zigzag wires was investigated. The design and architecture of the network of traps provided the framework for organizing well-defined planar assemblies of micro-particles and tethered biomolecules. A special feature of this platform is the ability to continuously tune the strength of the trapping potential through external magnetic fields that also render the traps to be mobile.
