Impact of aqueous suspension drops onto non-wettable porous membranes: Hydrodynamic focusing and penetration of nanoparticles

- Impact and penetration of nanoparticle suspension drops into porous membranes.
- Hydrodynamic focusing dominates other effects and water penetrates into membranes.
- Deposition patterns of seeding nanoparticles inside the membranes were observed.
- Theory for dynamic penetration of liquid in porous media due to drop impact is proposed.
