We first propose a model for a passive colloidal sphere which reproduces the correct rotational dynamics together with strong phoretic effect. This colloid solution model employs a multiparticle collision dynamics description of the solvent, and combines stick boundary conditions with colloid–solvent potential interactions. Asymmetric and specific colloidal surface is introduced to produce the properties of self-phoretic Janus particles. A comparative study of Janus and microdimer phoretic swimmers is performed in terms of their swimming velocities and induced flow behavior. Self-phoretic microdimers display long range hydrodynamic interactions with a decay of 1/r2, which is similar to the decay of gradient fields generated by self-phoretic particle, and can be characterized as pullers or pushers. In contrast, Janus particles are characterized by short range hydrodynamic interactions with a decay of 1/r3 and behave as neutral swimmers.}, cin = {IAS-2 / ICS-2}, ddc = {530}, cid = {I:(DE-Juel1)IAS-2-20090406 / I:(DE-Juel1)ICS-2-20110106}, pnm = {451 - Soft Matter Composites (POF2-451)}, pid = {G:(DE-HGF)POF2-451}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000340438600009}, pubmed = {pmid:25012361}, doi = {10.1039/C4SM00621F}, url = {https://juser.fz-juelich.de/record/154840}, }
