Abstract Surfactants are typically molecules whose key role is to lower the surface tension between liquid phases. At the same time, surfactants have not been considered as active elements that can set the liquids on motions or drastically alter their properties. In my talk, I will describe two new classes of surfactants based on appropriately functionalized nanoparticles or MOFs. These surfactants can be made responsive to various external fields (optical, magnetic, electric), can be used to manipulate, rotate, and assemble the droplets they enclose, and can stabilize droplets of very complex, non-spherical shapes. In one remarkable demonstration, our “nanosurfactants” are strong enough to actively pump the liquid they enclose out, into an immiscible outer liquid phase. All in all, nanoscale synthesis allows for the creation of completely new types of dynamic surfactant species, that are capable of change and also of performing useful work.
