Size Selectivity in Artificial Cilia–Particle Interactions: Mimicking the Behavior of Suspension Feeders

摘要: Inspired by the ability of marine suspension feeders to selectively capture small particles their hairlike cilia, we simulate interaction between artificial cilia and microscopic different sizes determine if a purely synthetic system can display analogous size-selective behavior. Our computational approach specifically models suspended in surrounding fluid adhesive filaments, which are anchored one end surface. Via this model, show that size selectivity arise as result hydrodynamic interactions system. The substantial reduction mobility large near surfaces leads failure capturing particles. Using simple analytical balance forces favors below critical for given cilia–particle interaction. findings provide guidelines designing be used sorting tran...
