Table 2.

Comparison of the percentage of membrane attachment for different protein coatings for close adhesion (d_j≤10 nm), and distances of d_j=10–100 nm. (For better comparison of the cell attachment, we defined the distance range for 90% of the attached membrane as the ‘d₉₀ value’. This table summarizes the cumulated distance distribution histograms for n=5–15 HEK cells shown in figure 8.)

fraction of membrane for dj=10–100 nm	78.7%	72.7%	76.9%	77.1%	59.4%	53.9%	49.9%
