This article describes a simple procedure to fabricate magnetically-responsive particles from as-prepared particles. Firstly, a magnetically-responsive, holmium-containing surfactant (DDAH) was prepared by mixing a commercially available surfactant and holmium(III) chloride hexahydrate. Subsequently, polydopamine (PDA) particles, which exhibit beautiful structural colors, were modified using the DDAH to afford PDA/DDAH particles. The magnetic behavior of the obtained PDA/DDAH particles was investigated. Furthermore, structural color changes of the materials prepared by PDA/DDAH particles under magnetic fields were also investigated.
