Autonomous magnetic devices for micro/nano particle handling

Abstract

-This article describes a lab practical based on the fabrication of thick hard magnetic films, their patterning at the micro-scale, their integration into microfluidic systems and their use in particle capture and sorting. It combines both standard and recently developed microfabrication techniques in order to create autonomous, downscaled magnetic micro-systems which can produce high magnetic forces on micro-and nano-sized objects. The lab practical was designed for Master students, but can be used as an introductory course for higher-level students starting in the field.
