Colloidal Matter and Devices

Colloidal particles exhibit unique properties that are precisely tailorable down to the atomic level. We develop and apply optical tools to trap, assemble and print colloidal particles as building blocks into colloidal superstructures, metamaterials and devices with desired functions. Inline metrology is being developed to measure structures, dynamics and properties of the colloidal matter at single-particle resolution. We aim to develop nanofactories for colloidal metamaterials, to innovate colloidal devices and to elucidate how matter organizes.
