Abstract：
We report chemically fueled oscillations of vesicles. The population cycling of vesicles is driven by their self-reproduction and collapse within a biphasic reaction network involving the interplay of molecular and supramolecular events. We studied the oscillations on the molecular and supramolecular scales and tracked vesicle populations in time by interferometric scattering microscopy and dynamic light scattering. Complex supramolecular events were observed during oscillations─including vesicle reproduction, growth, and decomposition─and differences in the number, size, and mass of aggregates can often be observed within and between pulses. This system\'s dynamic behavior is reminiscent of a reproductive cycle in living cells.
摘要：
我们报告了囊泡的化学燃料振荡。囊泡的种群循环是由它们在双相反应网络中的自我繁殖和崩溃驱动的，该网络涉及分子和超分子事件的相互作用。我们研究了分子和超分子尺度上的振荡，并通过干涉散射显微镜和动态光散射及时跟踪了囊泡种群。在振荡期间观察到复杂的超分子事件─包括囊泡繁殖，增长,和分解-以及数量的差异，尺寸,通常可以在脉冲内部和脉冲之间观察到聚集体的质量。这个系统的动态行为让人想起活细胞中的生殖周期。
