Physical characterization of the silk fibroin nanoparticles (SFNs) and naringenin-loaded silk fibroin nanoparticles (NAR-SFNs) prepared from three NAR/SFN ratios (1:4, 1:2 and 1:1).
| Sample | Z-Average (nm) | PdI | Zeta Potential (mV) | Electrophoretic Mobility (µm cm/Vs) |
|---|---|---|---|---|
| SFNs | 148.4 ± 1.3 a | 0.11 ± 0.01 a | −39.1 ± 0.7 a | −3.06 ± 0.05 a |
| NAR-SFNs 1:4 | 157.6 ± 0.9 b | 0.12 ± 0.01 a | −37.9 ± 1.5 a | −2.97 ± 0.12 a |
| NAR-SFNs 1:2 | 164.0 ± 1.1 c | 0.17 ± 0.01 b | −37.8 ± 1.2 a | −2.96 ± 0.09 a |
| NAR-SFNs 1:1 | 180.1 ± 2.6 d | 0.22 ± 0.01 c | −30.5 ± 0.7 b | −2.39 ± 0.05 b |
Mean Values ± SD (standard deviation) (n = 3). a,b,c,d Means within each column with different letters are significantly different (p < 0.05), Tukey’s test.
