When man-made self-powered micromotors swim in a gradient of chemical fuel, they experience a chemical attraction towards the fuel and deviate from their otherwise random motion. As S. Sanchez et al. describe in their Communication on page 5552 ff., self-propelled microjets and microparticles change their trajectory when hydrogen peroxide fuel is added to the solution in which they navigate, a response similar to the chemotactic behavior of some living organisms. (The authors thank Dr. Träger for designing the image.)
