We experimentally investigate the assembly behavior of sub-micron colloidal particles in the spherical confinement of an emulsion droplet as a function of the number of constituent particles and the time scale available for the assembly process.
Colloidal lithography serves as a simple yet efficient tool to obtain wafer-scale surface nanostructures. The process takes advantage of the ability of colloidal particles to form ordered monolayer structures at liquid interfaces.
We use colloidal self-assembly techniques to create materials and surfaces with defined nanostructural and hierarchical architectures which mimic the optical properties found in nature.
we develop simple strategies to assemble such colloidal monolayer with high precision at the air/water interface and investigate their structure as a function of the physicochemical properties of the individual particles.
Research in the self-assembled materials group gravitates around the self-organization of colloidal particles. We seek a fundamental understanding of self-assembly processes to create defined nanostructured materials and surfaces. We investigate the emergence of functional properties from such structures, for example to control the wetting of a surface, to create vivid structural coloration, or to fabricate plasmonic nanostructure arrays.
