在生物医学和材料科学中的潜在应用推动了对均匀多功能磁性颗粒的兴趣。在这里,我们展示了高度定制的纳米级和微米级的磁性聚合物复合粒子的制造使用基于模板的方法。通过化学接枝和蒸发Pt沉积进行颗粒的区域特异性表面功能化。在水和过氧化氢中证明了通过施加磁场对颗粒的操纵。
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.
