    • The ratio of motional resistance (R1) and dissipation (D) should be constant (based on the Butterworth-van Dyke equivalent circuit). It is experimentally observed, however, that the ratio can fluctuate slightly.

    • Historically, the Df ratio was first used in the context of nanotribology. For a layer of rigid spheres adsorbed to a solid surface from vacuum, the Df ratio is proportional to the momentum relaxation time or "slip time". For details, see:(a)

    • Direct evidence for 2D crystallization on SLB-coated QCM-D sensors is still missing. It may potentially be obstructed by the nanometer-scale roughness of the sensor surface, as demonstrated for other proteins; see ref 28.

    • Such a dependence was found in the experiments reported in ref 25. However, these experiments were conducted on vesicles, which are much softer than the particles investigated here. In this case, the deformability of bulk of the vesicles did play a role in addition to the properties of the contact zone.

    • The pressure gradient has units of N/m, because the simulation is conducted in two dimensions. Otherwise, an integrated pressure gradient would be a force.
