Concentration cycles are important for bonding of basic molecular building components at the emergence of life. We demonstrate that oscillations occur intrinsically in precipitation reactions when coupled with fluid mechanics in self-assembled precipitate membranes, such as at submarine hydrothermal vents. We show that, moreover, the flow of ions across one pore in such a prebiotic membrane is larger than that across one ion channel in a modern biological cell membrane, suggesting that proto-biological processes could be sustained by osmotic flow in a less efficient prebiotic environment. Oscillations in nanoreactors at hydrothermal vents may be just right for these warm little pores to be the cradle of life.

自组装沉淀膜的固有浓度循环和高离子通量。

浓度循环对于生命出现时基本分子构建成分的键合非常重要。我们证明，当与自组装沉淀膜中的流体力学耦合时，例如在海底热液喷口处，振荡在沉淀反应中固有地发生。此外，我们显示，在这样的益生元膜中穿过一个孔的离子流大于在现代生物细胞膜中穿过一个离子通道的离子流，这表明原生物过程可以通过渗透效率较低的益生元中的渗透来维持。环境。纳米反应器在热液喷口处的振荡可能恰好使这些温暖的小孔成为生命的摇篮。
