Abstract Biomolecular condensates formed through liquid-liquid phase separation play key roles in intracellular organization and signaling, yet their function in extracellular environments remains largely unexplored. Here, we establish a model using heparan sulfate, a key component of the extracellular matrix, to study extracellular condensate-cell interactions.

The motion of catalytically active colloids approaching a surface Catalytic microswimmers typically swim close to walls due to hydrodynamic and/or phoretic effects. The walls in turn are known to affect their propulsion, making it difficult to single out the contributions that stem from particle-based catalytic propulsion only, thereby preventing an understanding of the propulsion mechanism.
