We initially prepared the TiO2 particles by a modification of our previously published method. To obtain magnetic Au@Ni@TiO2 micromotors, TiO2 particles were coated with a 10 nm nickel layer and then with 30 nm layer of gold. This photocatalytic micromotor can move efficiently in both, water and peroxide when irradiated with UV light, based on photocatalytic chemical reaction.
