ANISOTROPIC MAGNETIC COMPOSITE WITH CUSTOMIZED MICROSTRUCTURATION FOR MICROFLUIDIC DEVICES

Abstract

Anisotropic magnetic composite polymers are promising materials to implement magnetophoretic functions in microfluidic devices. Besides microfabrication advantages, they offer interesting modular magnetic properties. In particular, the custom microstructuration of particles within the polydimethylsiloxane (PDMS) matrix, permits to create powerful magnetic functions. In the present work, we report that self-ordering of particles within the matrix permits either to improve existing magnetophoretic functions, or to create original ones, such as arrays of magnetic micro-traps resulting from individual 1D-magnetic flux micro-concentrators embedded in the matrix.
