Various functionalization strategies were used: (a) CD4-tip vs. anti-CD4-mica (generalized extreme value: 144.91 ± 84.18 pN; mean value: 220.85 ± 156.29 pN; n=1135); (b) anti-CD4-tip vs. CD4-mica (generalized extreme value: 51.22 ± 34.64 pN; mean value:79.72 ± 59.36 pN; n=1114); (c) anti-gp120-tip vs. gp120-mica (generalized extreme value: 108.84 ± 83.26 pN; mean value: 185.44 ± 155.21 pN; n=1724); (d) gp120-tip vs. anti-gp120-mica (generalized extreme value: 89.87 ± 44.63 pN; mean value: 121.52 ± 66.12 pN; n=632).
