Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

open access: yesAdvanced Materials Interfaces, EarlyView.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...
