Nanoparticle Control and Transport using Mobile Magnetic Domain Wall Traps
Geoffrey Beach, Assistant Professor, Department of Materials Science & Engineering
This research seeks to develop an on-chip system for the capture, manipulation, and transport of individual magnetic nanoparticles for applications in, e.g., magnetic sorting of biomolecular entities.
It is expected that a working prototype of a nanoparticle transport system with integrated single-particle detection will be developed and demonstrated. The results are widely relevant to a variety of key research areas including cell sorting, pathogen detection, chemical and biological agent detection, and controlled nanoscale assembly.
