Light microscopy of NaCl crystals formed after drying a droplet of a solution containing 375 mM NaCl, 5 mM Tris–HCl buffer and 5 mg/mL fibrinogen. (A) Overview image of the sample (×20 magnification), (B) detail on salt (×100 magnification), (C) detail on the halo region (×200 magnification) and (D) detail of deposits found away from the bigger crystals on the substrate surface (×500 magnification)
