These particles are then partly covered with platinum and suspended in hydrogen peroxide to become chemically propelled, active particles. First, it is shown that 3D-printing can indeed be used to fabricate active particles, by fabricating some relatively simple 4 µm spheres. Subsequently, different helical particles are designed and fabricated to discover that some designs can be printed consistently with the same outcome and that some cannot. A consistently printed helical particle is then analyzed to investigate the relationships between its active motion and its helical shape.Show less
