(a–c) The histogram of the location of newly formed clusters with total 1,000,000 (a), 1,500,000 (b), or 2,000,000 (c) microspheres containing different percentage of dimers (t = 1 s). (d–f) The simulated coffee-ring pattern based on total 1,000,000 (d), 1,500,000 (e), or 2,000,000 (f) microspheres containing different percentage of dimers.
