In this experiment, we demonstrate how the velocity of self-propelled spheroids can be externally tuned by adjusting the light irradiation intensity.
As the irradiation intensity increases, the degree of photoisomerization of surfactant molecules rises, which strengthens the surrounding diffusioosmotic flow.
This enhancement boosts the propulsive force acting on the spheroids, resulting in progressively faster motion.

👉 This video highlights how light-controlled diffusioosmosis enables external regulation of active particle dynamics, with relevance to active matter, microfluidics, and photoactive materials.
