Table 2.
Wound dressing extracts were prepared in caso-bouillon with pH 6.0, 7.0, 8.0, or 9.0 by incubation for 24 h at 37 °C
| Wound dressing | Basic material | Active ingredient | Effect on actual pH value at pH | |||
|---|---|---|---|---|---|---|
| 6.0 | 7.0 | 8.0 | 9.0 | |||
| Alginate + ionic-Ag | Alginate | Ionic silver | 5.7 | 6.5 | 7.2 | 7.7 |
| Alginate + nano-Ag | Alginate | Nano-crystalline silver | 7.6 | 7.9 | 8.2 | 8.4 |
| CMC with Ag+ | Sodium carboxymethyl cellulose (CMC) | Ag+ | 5.6 | 6.1 | 7.1 | 8.1 |
| PU-foam with TLC/Ag+ | Polyurethane (PU) foam with TLC (lipidocolloid matrix) | Ag+ | 6.2 | 7.2 | 7.8 | 8.6 |
Afterwards, the actual pH was determined
