Colloids with chemical distinct and precisely located patches, so called “patchy particles”, are expected to be useful for the construction of open structured colloidal architecture. However, most synthetic pathways only generate mono-functionality lying on patches so far, which limit their more sophisticated potential applications, such as artificial self-replicating colloids. Patch particles bearing dual functionalities both on patches and matrixes are achieved. By attaching two orthogonal DNAs on each part, spatial and temporal controlled self-assembly are demonstrated. And the patch particles can behavior two-stage assembly/melting when tuning the length of “stick end” on patches and matrixes.
