A current challenge in the field aims at using friction asymmetry to steer the motion of microscopic particles. Here we show that lithographically shaped magnetic microtriangles undergo a series of complex transport modes when driven by a precessing magnetic field, including a surfing-like drift close to the bottom plane. In this regime, we exploit the triangle asymmetric shape to obtain a transversal drift which is later used to transport the microtriangle in any direction along the plane. We explain this friction-induced anisotropic sliding with a minimal numerical model capable to reproduce the experimental results. Due to the flexibility offered by soft-lithographic sculpturing, our method to guide anisotropic-shaped magnetic microcomposites can be potentially extended to many other field responsive structures operating in fluid media.7 p.application/pdfengcc-by (c) Junot, Gaspard, et al., 2022http://creativecommons.org/licenses/by/3.0/es/Propietats magnètiquesNanopartículesFriccióMagnetic propertiesNanoparticlesFrictioninfo:eu-repo/semantics/article7270872023-03-13info:eu-repo/semantics/openAccess
