(a) Evaporation drives radial slit flow and cell dispersion. (b)–(d) The bottom view of the settling and organization of cells over 5 min. (e)–(g) The corresponding illustrated cross-sectional side view of (b)–(d) shows the settling and organization of cells over 5 min. If there are gaps between cells at the bottom, cells above will try to fill the gaps and eventually settle at the bottom of the well.
