Micro-/nano-motors (MNMs) or swimmers are minuscule machines that can convert various forms of energy, such as chemical, electrical, magnetic into motion. These devices have attracted significant attention owing to their potential application in a wide range fields drug delivery, sensing, and microfabrication. However, diverse shapes, sizes, structural/chemical compositions, the development MNMs faces several challenges, understanding structure-function relationships, which is crucial for achieving precise control over motion within complex environments. In recent years, machine learning techniques shown promise addressing these challenges improving performance MNMs. Machine analyze large amounts data, learn from patterns, make predictions, thereby enabling navigate environments, avoid obstacles, perform tasks with higher efficiency reliability. This review introduces current state-of-the-art MNM research, particular focus on employing understand manipulate navigation locomotion Finally, we discuss opportunities this field suggest future research directions.
