There is high interest in new colloidal and polymerization methods that will go beyond the traditional emulsion polymerized systems involving lithographic and also extrusion methods. The ability to control the microstructure and composition enables new functionality different from colloids prepared in solution. The ability to hierarchically prepare and process layers mean that new materials and material order can be produced during the processing stage. This results in a more quantitative and uniform behavior for actuation, controlled drug release, peristaltic motion, and flow behavior. Herein we report the use of layer-fabrication methods from the molecular all the way to macroscopic that results in hierarchical and high throughput methods. The advantage os such control also enables the use of isotropically melt polymer layers through a polymer extrusion process. This has proven to be versatile for the preparation of colloidal particles that are capable of stimuli response. These polymer particles can be made by reactive ion etching lithography or via roll-to-roll multilayer processing. This will enable in the future the high throughput fabrication of such particles with the built-in modified properties expected.
