Patchy particles with well defined symmetries and specific interactions are desirable to construct micro-structured materials. We develop a method to fabricate particles with various numbers of patches, n=1�7 and higher, that adopt spherical, linear, triangular, tetrahedral, trigonal dipyramidal, octahedral or pentagonal dipyramidal symmetries. The patchy particles are formed from clusters using a two-stage swelling method followed by polymerization. Patches can also be site-specifically coated with oligonucleotides, enabling a reversible and controllable attraction between patches on different particles.
