由反应和扩散之间的相互作用产生的化学浓度波动，在许多远离平衡的化学系统中发生。在适当选择的聚合物凝胶中，这些波产生机械力，从而导致运动。当系统的一个组件是光敏的，光可以用来调制和控制这些波。在这篇概念文章中，我们研究了这种系统的各种形式的光控制，特别关注Belousov-Zhabotinsky振荡化学反应。我们考虑的现象包括图像存储和图像处理，反馈控制和反馈诱导的波聚类，以及趋光和避光运动。其中一些现象在生物系统中有类似的或潜在的应用。
Waves of chemical concentration, created by the interaction between reaction and diffusion, occur in a number of chemical systems far from equilibrium. In appropriately chosen polymer gels, these waves generate mechanical forces, which can result in locomotion. When a component of the system is photosensitive, light can be used to modulate and control these waves. In this Concept article, we examine various forms of photo‐control of such systems, focusing particularly on the Belousov–Zhabotinsky oscillating chemical reaction. The phenomena we consider include image storage and image processing, feedback‐control and feedback‐induced clustering of waves, and phototropic and photophobic locomotion. Several of these phenomena have analogues in or potential applications to biological systems.
