Swap transactions : Bidirectional spontaneous transfer of gold nanoparticles coated with stimuli‐responsive polymer brushes across oil–water interfaces has been implemented (see picture). The water‐to‐oil transfer of the gold nanoparticles is dictated by the ionic strength in water, while the nanoparticle oil‐to‐water transfer occurs only when the environmental temperature is reduced below 5 °C.
