Biomimetic active droplets <i>via</i> enzymatically driven reactions

Millions of enzyme-catalysed reactions happen every second in the compositionally complex crowded environment of a single living cell. Here, we introduce a model system to mimic the high crowding and metabolic rates found in living cytoplasm, while maintaining relatively simple compositions. We demonstrate how this system can be used to study biochemical phenomena in a realistic controlled environment, and to study the novel physics of active liquids.
