Chemically triggered metal-ion signals to generate pulsed functions in supramolecular multicomponent networks

活的生物系统以高度相互依赖的方式使用化学信号进行通信。脉冲钙离子信号的使用是一种复杂的方法，使用频率编码的信息传递来选择性地触发广泛的细胞过程。根据生物模型，功能性人工多组分系统将通过金属离子脉冲进行操作。在这里，燃料酸的离散添加首先暂时触发金属离子的释放，然后是它们的回收，导致金属超分子结构的脉冲状重新分选成暂时的功能单元，然后是其衰变。该方法的潜力是通过燃料酸的时间调制添加来执行在高频率和低频率下的催化反应或频率编码的分子逻辑过程。这种额外的转向维度，接近于通过钙离子脉冲对生物任务的动态调节，有望进入脉冲的、后来的频率调制过程控制。

Living biological systems communicate in a highly interdependent manner using chemical signals. The use of pulsed calcium ion signals is a sophisticated method to selectively trigger a wide range of cellular processes using frequency-encoded information transfer. Following the biological model, functional artificial multicomponent systems are to be operated via metal ion pulses. Here, the discrete addition of a fuel acid temporarily triggers first a release of metal ions followed by their retrieval, resulting in a pulse-like re-sorting of the metallosupramolecular structure(s) into a temporary functional unit followed by its decay. The potential of this process is to perform either catalytic reactions at high and low frequency or frequency-encoded molecular logic processes via the time modulated addition of the fuel acid. This additional dimension of steering, which is close to the dynamic regulation of biological tasks by calcium ion pulses, promises an entry into pulsed, later frequency modulated process control.
