Table 1 Quantification of NH2 groups per area for different spacer molecules on cp-titanium and on TiO2 powder (amount per powder weight in [nmol/mg] in parenthesis)
Substrate | Number of primary NH2-groups per nm2 | ||
|---|---|---|---|
APMS | Diamino-APMS | Triamino-APMS | |
cp-Ti disc | 156 ± 16 | 162 ± 12 | 134 ± 22 |
TiO2 powder | 20.0 ± 0.5 (84.9 ± 2.1) | 18.7 ± 0.5 (78.7 ± 2.0) | 17.0 ± 0.3 (71.3 ± 1.3) |
