We investigate the Belousov–Zhabotinsky (BZ) reaction in an attempt to establish a basis for computation using chemical oscillators coupled via inhibition. The system consists of BZ droplets suspended in oil. Interdrop coupling is governed by the non-polar communicator of inhibition, Br₂. We consider a linear arrangement of three droplets to be a NOR gate, where the center droplet is the output and the other two are inputs. Oxidation spikes in the inputs, which we define to be TRUE, cause a delay in the next spike of the output, which we read to be FALSE. Conversely, when the inputs do not spike (FALSE) there is no delay in the output (TRUE), thus producing the behavior of a NOR gate. We are able to reliably produce NOR gates with this behavior in microfluidic experiment.

Belousov-Zhabotinsky 微滴的可配置 NOR 门阵列。

我们研究了 Belousov–Zhabotinsky (BZ) 反应，试图为使用通过抑制耦合的化学振荡器进行计算奠定基础。该系统由悬浮在油中的 BZ 液滴组成。_{点间耦合由抑制的非极性通讯器 Br 2}控制。我们将三个液滴的线性排列视为或非门，其中中心液滴是输出，另外两个是输入。输入中的氧化尖峰（我们定义为 TRUE）会导致输出的下一个尖峰出现延迟（我们将其读为 FALSE）。相反，当输入不尖峰 (FALSE) 时，输出没有延迟 (TRUE)，从而产生 NOR 门的行为。我们能够在微流体实验中可靠地生产具有这种行为的或非门。
