Description
Since the development of the first generation of self-propelled nanomotors, the field has undergone extensive exploration. A wide range of nanomotors has been synthesized, varying in materials, shapes, sizes, and propulsion mechanisms [1]. However, this diversity also introduces new challenges and raises fundamental questions, particularly regarding practical applications. Current research is primarily focused on areas such as drug delivery, pollutant degradation, sensing, and other fields that demand thorough investigation. These domains require comprehensive examinations of dynamics within confined spaces characterized by diverse obstacles and geometries, such as spheres, channels, and pores [2-4]. In this study, we analyzed the effects of confinement on the photocatalytic efficiency and collective motion behavior of different active colloids. As a result, this work introduces a novel “lab-in-a-drop” approach, which facilitates the exploration of new frontiers in understanding nanomotor behavior under confinement and in three-dimensional spaces, while advancing their potential applications in biomedicine, sensing, and environmental systems.
