Structure parameter, FPO-loading efficiency and zeta potential analyses of the synthesized samples (HMSNs, HMSNs-NH2 and FPO@HMSNs-PAA).
| Sample a | SBET (cm3 g−1) | Vpore (cm3 g−1) | Dpore (nm) | FPO Loading Content | Zeta Potential b (mV) |
|---|---|---|---|---|---|
| HMSNs | 1166 | 0.84 | 2.7 | / | −33.7 ± 1.3 |
| HMSNs-NH2 | 1033 | 0.71 | 2.5 | / | +36.1 ± 3.1 |
| FPO@HMSNs | 282 | 0.28 | 2 | 54.90% | −42.4 ± 1.9 |
| FPO@HMSNs-PAA | 94 | 0.13 | / | 38.32% | −56.5 ± 2.5 |
a Data are presented as means ± SDs (n = 3). b Zeta potential were measured in PBS (pH = 7.40) at room temperature.
