Finding the right angle : The contact angle of nanoparticles at the water/oil interface can be engineered close to 90° by capping with ligands containing carboxylic ester terminal groups. This drives the nanoparticles to self‐assemble into close‐packed films (see picture), and thus provides the opportunity to create two‐ or three‐dimensional homo‐ or heterogeneous nanostructures for electronic, optoelectrical, and magnetic applications.
