Interest in uniform multifunctional magnetic particles is driven by potential applications in biomedical and materials science. Here we demonstrate the fabrication of highly tailored nanoscale and microscale magneto-polymer composite particles using a template based approach. Regiospecific surface functionalization of the particles was performed by chemical grafting and evaporative Pt deposition. Manipulation of the particles by an applied magnetic field was demonstrated in water and hydrogen peroxide.
人们对多功能磁性粒子的兴趣源于其在生物医学和材料科学领域的潜在应用。在此，我们展示了一种基于模板的方法，可制备高度定制的纳米级和微尺度的磁聚合物复合材料粒子。通过化学接枝和蒸发 Pt 沉积，对粒子进行了区域选择性表面功能化。在水和过氧化氢中，通过施加磁场对粒子进行了操控。
