Researchers have developed various assembly approaches, including self-assembly and electric/magnetic field directed assembly, to build diverse colloidal matters. These techniques feature high throughput but with limited structural configurations. Specifically, some of the techniques highly rely on the physical performance of the colloidal particles. In new work, researchers have developed a versatile colloidal assembly strategy – termed opto-thermophoretic assembly (OTA) – to build artificial colloidal matter in a wide range of colloidal materials, sizes, and shape.
