Fabrication and characterization of the triblock patchy particles. (a) Schematic illustration of the “sandwich” micro-contact printing method for creating the trivalence on spherical silica microparticles. The proteins to be printed on the particles are illustrated in red and green. A protein incubation step follows the microcontact printing to coat the particles either with BSA for passivation or with BSA-biotin for uniform ligand coating. (b) Overlaid epifluorescence images of 3 μm triblock Janus particles. Scale bar: 5 μm.
