Tubular MicromotorsRohrförmiger Mikromotor

The distinctive feature of the hollow cylinder (tube) structure lies in its ability to possess different functionalities to the inner pore, tube wall, and outer surface. By employing a unique methodology combining template photopolymerization and alternate layer-by-layer assembly techniques, we synthesized polymer-based tubular micromotors in which platinum nanoparticles (PtNPs) or catalase were positioned on the inner pore wall, enabling them to self-propel in water by jetting oxygen bubbles. Surface modifications on the tube's exterior serve as capture agents for targeted substances or pathogens (viruses and bacteria) and act as self-stirring catalysts. For catalase-tube motors, velocity control is achievable through pH, temperature, and light modulation. These micromotors hold promise for applications in medical and diagnostic fields.
