Self-assembly of nanoparticles on liquid-metal droplets (see image) provides a simple, effective approach to electronic devices with nanoscale control of the metal/nanoparticle junctions. This approach enables the inexpensive fabrication of a large number of devices and deposition on large-area substrates.
