Abstract

A microfluidic method that allows direct visualization of the dynamics of colloidal crystal growth on curved interfaces was investigated. A three-channel hydrodynamic focusing device in order to control particle delivery and assembly at the scale of individual shells was designed. It was observed that the energetic barriers to the interfacial crystal growth and the organization can be overcome by targeted delivery of colloidal particles through hydrodynamic flows. The method provides new applications and strategies for making advanced patterned colloidal shells of controlled size, shape and composition.
