Table 1.
The initial and total release of gentamicin in 57 hours
| Specimen | Total drug-loaded (μga/one disc) | Initial release (μgb) | Total release (μg) |
|---|---|---|---|
| NT-G80 | 1519.27 | 79.01 | 91.45 |
| NT-G120 | 1524.25 | 85.96 | 98.73 |
| NT-G160 | 1587.46 | 132.98 | 142.57 |
| NT-G200 | 1605.08 | 143.51 | 157.85 |
a
Notes: The amount of gentamicin retained in the nanotubes after the initial wash: 2 mg × η (the loading efficiency);
b
the amount of drug released in the initial high release period before the rate of drug release became approximately constant.
Abbreviation: NT-G, gentamicin-loaded nanotubes.
