Stimuli‐Responsive Reversible Transport of Nanoparticles Across Water/Oil Interfaces

Abstract

To cap it all: With the aid of stimuli-responsive polymer capping, gold nanoparticles (Au-NPs) can be highly colloidally stable in both aqueous and organic media. They spontaneously and reversibly cross water/oil interfaces in both directions upon formation of a biphasic salty water–oil system (see picture).
