Abstract: Clusters in the form of aggregates of a small number of elemental units display structural, thermodynamic, and dynamic properties different from those of bulk materials. We studied the kinetic pathways of self-assembly of "Janus spheres" with hemispherical hydrophobic attraction and found key differences from those characteristic of molecular amphiphiles. Experimental visualization combined with theory and molecular dynamics simulation shows that small, kinetically favored isomers fuse, before they equilibrate… Show more

“…The self-assembly of patchy particles into a target structure can be viewed as a "colloidal reaction" or more generally as "supracolloidal chemistry" 40 . As in conventional chemical reactions, colloidal particles with a particular morphology and binding capacity are used as reagents and mixed together stoichiometrically.…”

“…The self-assembly structures of colloidal systems are very important to understand biological and chemical systems, like proteins and solutions 4 . Experimental and computational researches show that Janus spheres present cluster formation and properties different from bulk systems 5,6 . When structured in equilibrated aggregates, the charge asymmetry of each particle is preserved 5 .…”

“…Externally applied light, magnetic, electric, and acoustic fields can drive symmetric particles into ordered arrays (4)(5)(6)(7). Colloidal Janus particles selfassemble into complex structures by various mechanisms (8)(9)(10)(11)(12). However, in these examples the particle aggregates hardly approach the complexity of assemblies of living organisms; the interactions are passive responses to local forces and external fields with very limited interparticle communication or active response to the behavior of nearest neighbors.…”
