Dynamic assembly: Peanut-shaped hematite colloid motors activated by light can readily be organized into one-dimensional colloid ribbons, which exhibit a positive phototactic behavior. The direction, speed and size of as-formed active colloid ribbons can be modulated by using light and surface faction of colloidal suspensions.
