Modular Micromotor Fabrication with Self‐Focusing Lithography

Synthetic Janus micro/nanomotors can efficiently convert ambient energy into asymmetrical self-propulsive force, overcoming random thermal fluctuations and enabling autonomous migration. Further modifications to the motors can equip them with different functional modules to meet different needs. However, developing a versatile and high-yield fabrication method for multifunctional Janus micromotors remains challenging. In this study, a modular fabrication approach for micromotors with a particle-tip structure based on the self-focusing lithography induced by an array of TiO
