# Evaporation-Driven Assembly of Colloidal Particles

Vinny Manoharan wrote a paper describing how clusters of small (d=844nm) polystyrene spheres could be formed in reproducible configurations by dispersing them in a toluene-water emulsion and then preferentially evaporating the toluene. The geometries that formed minimized the second moment of the cluster as defined by $\mathcal{M}=\sum_{i}||r_i-r_o||^2$. This paper examines the theoretical basis for these findings.
