“…Artificial chemical computing has been the topic of several contributions in recent years. Hjemlfelt et al [21], Okamoto et al [30], and Mills et al [28], for example, investigated the possibilities of realizing artificial neural networks or Turing machines in vitro; Arkin [5] discovered computational functions in biochemical reaction networks; Adleman realized a DNA-based solution of a combinatorical problem [3]; and Adamatzki et al [2,32,33] proposed the use of oscillating reactions like the Belousov-Zhabotinsky reaction for mobile robot control. Artificial chemical computing has been used for control tasks, especially for mobile robots.…”
