Snapshots of the deposits of citrated (a) or PEGylated (b) IONPs around a single magnetized micropillar in the microfluidic channel under hydrodynamic flow and externally applied magnetic field of intensity H₀ = 13.5 kA/m at the nanoparticle volume fraction ϕ₀ = 0.17 ± 0.03 vol.% The rows of (a) and (b) correspond to different elapsed times: from the top to the bottom t = 0, 10, 20, 40, and 60 min; the columns correspond to different flow speeds u = 0, 0.714, 1.43, 2.14, 2.85, 5.23, 7.61, and 10 mm/s.
