Hydrodynamic interactions are captured by a particle-based mesoscopic simulation method. At vanishing relative velocity, the equilibrium repulsive force-distance curve is obtained. At large drag velocities, in contrast, we find an apparent attractive force for departing colloids along the dragging direction. The deformation, in the close encounter of colloids, and the energy dissipation are examined as a function of the drag velocity and their separation.}, keywords = {J (WoSType)}, cin = {ICS-2 / IAS-2}, ddc = {550}, cid = {I:(DE-Juel1)ICS-2-20110106 / I:(DE-Juel1)IAS-2-20090406}, pnm = {BioSoft: Makromolekulare Systeme und biologische Informationsverarbeitung}, pid = {G:(DE-Juel1)FUEK505}, shelfmark = {Physics, Multidisciplinary}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000296288500015}, doi = {10.1103/PhysRevLett.107.158301}, url = {https://juser.fz-juelich.de/record/16776}, }
