We demonstrate that a transition from a compact geometry (sphere) to a structured geometry (several spheres connected by nanoconduits) in nanotube-vesicle networks (NVNs) induces an ordinary enzyme-catalyzed reaction to display wavelike properties. The reaction dynamics can be controlled directly by the geometry of the network, and such networks can be used to generate wavelike patterns in product formation. The results have bearing for understanding catalytic reactions in biological systems as well as for designing emerging wet chemical nanotechnological devices.
我们证明，在纳米管-囊泡网络（NVNs）中，从致密几何结构（球体）到结构化几何结构（通过纳米管道连接的多个球体）的转变会促使普通的酶催化反应呈现出波状特性。反应动力学可以直接由网络的几何结构控制，并且这样的网络可用于在产物形成过程中产生波状图案。这些结果对于理解生物系统中的催化反应以及设计新兴的湿化学纳米技术装置具有重要意义。
