In this thesis, patterning methods to fabricate various functional particle patterns on substrates were developed, with the main aim of modifying the properties and functions of the substrates. Two classes of model substrates were selected; topographically patterned and smooth substrates. For the first model system, i.e., topographically patterned substrates, replication molding was used to topographically pattern substrates of different materials. The topographically patterned substrates, including TiO2, block-copolymer substrates (PS-b-P2VP and PS-b-P4VP), and microrings (TiO2 and Au), were then used to assemble silica (SiO2) microparticles for functional applications. By the assembly of microparticles on topographically patterned substrates, the wettability of the former could be reversibly switched from hydrophobic to hydrophilic. Moreover, a platform for the preparation of Janus particles by orthogonal functionalization of the top and bottom sides of microparticles assembled on topographically patterned substrates was developed. Clusters of superparamagnetic nanoparticles were stamped on the second class of model substrates, i.e., smooth silanized silicon substrates. A capillary stamping approach combined with an external permanent magnetic field or electromagnets was realized to print magnetic nanoparticle-based inks. In this way, ordered arrays of clusters of magnetic nanoparticles were produced.
