Self-Assembly of Colloidal Molecules due to Self-Generated Flow
Self-Assembly of Colloidal Molecules due to Self-Generated Flow
The emergence of structure through aggregation is a fascinating topic and of both fundamental and practical interest. Here we demonstrate that self-generated solvent flow can be used to generate long-range attractions on the colloidal scale, with subpiconewton forces extending into the millimeter range. We observe a rich dynamic behavior with …
