We demonstrate here a novel approach to realize fast and reversible micro-sieving operations by manipulating and transporting colloidal chains via mobile domain walls in a magnetic structured substrate. We show that this technique allows one to precisely move and sieve non-magnetic particles, to tweeze microscopic cargos or to mechanically compress highly dense colloidal monolayers.7 p.application/pdfeng(c) Martinez Pedrero, Fernando et al., 2015Col·loidesNanotecnologiaColloidsNanotechnologyinfo:eu-repo/semantics/article6523682015-05-25info:eu-repo/semantics/openAccess25685897
