In situ liquid cell scanning transmission electron microscopy probes seeded growth in real time. The growth of Pd on Au nanocubes is monitored as a model system to compare growth within a liquid cell and traditional colloidal synthesis. Different growth patterns are observed due to seed immobilization and the highly reducing environment within the liquid cell.
LC-STEM was used to deposit palladium metal via electron beam deposition onto gold nanocube seed particles to form bimetallic nanoparticles.
