Multicomponent self-assembly has been explored to create novel metamaterials from nanoparticles of different sizes and compositions, but the assembly of nanoparticles with complementary shapes remains rare. Recent binary assemblies were mediated by DNA base pairing or induced by solvent evaporation. Here, we introduce depletion-induced self-assembly (DISA) as a novel approach to constructing tunable binary lattices.

- * In situ aberration-corrected scanning transmission electron microscopy (STEM) and molecular dynamics simulations were used to study AuCoCuNiPt nanoparticles' thermal behavior from 298 to 973 K.
- * The study revealed strong structural changes and phase separation in the nanoparticles at high temperatures, highlighting active atomic diffusion and providing insights into the kinetic and thermodynamic effects that can guide future nanomaterial synthesis.
Depletion-induced self-assembly is routinely used to separate plasmonic nanoparticles (NPs) of different shapes, but less often for its ability to create supercrystals (SCs) in suspension. Therefore, these plasmonic assemblies have not yet reached a high level of maturity and their in-depth characterization by a combination of in situ techniques is still very much needed. In this work, gold triangles (AuNTs) and silver nanorods (AgNRs) are assembled by depletion-induced self-assembly.
