Reshapable magnetic particles for morphology-controlled soft systems

Abstract

Spherical polymeric particles are essential in a wide range of applications, from fundamental self-assembly to bioseparation technologies, with well-established synthetic methodologies. However, incorporating functional components into polymeric matrices to enhance their properties remains a significant challenge, especially when uniformity is required. In this study, we introduce a simple and versatile emulsion evaporation method to fabricate magnetic-loaded polymeric microparticles with exceptional malleability. These composite particles maintain their magnetic functionality while being reshaped into ellipsoids through mechanical stretching. This scalable and straightforward approach offers precise control over particle morphology, offering broad potential for applications in soft robotics, drug delivery, and other magnetically responsive systems.
