Characterisation parameters of chitosan nanoparticles and Cur-CS nanoparticles.
| Chitosan/curcumin ratio | Mean particle size (nm) | Zeta potential (mV) | Encapsulation efficacy (%) | Drug loading (%) | |
|---|---|---|---|---|---|
| Cur-CS nanoparticles | 1 : 1 | 365.8 ± 15.1a | ND | 64.3 ± 3.2a | 31.1 ± 3.9a |
| 1 : 0.75 | 332.4 ± 9.4b | 42.1 ± 3.0 | 77.2 ± 3.6b | 46.7 ± 2.9b | |
| 1 : 0.5 | 339.4 ± 10.8b | ND | 81.9 ± 4.5b | 44.3 ± 2.2b | |
| Chitosan nanoparticles | 239.2 ± 6.4c | 53.3 ± 2.6 | — | — |
Data are presented as mean ± SD (n = 3) and analysed using one-way ANOVA and post hoc Duncan multiple test. For each parameter, means within a column with different roman letters were significantly different (p < 0.05) from each other. Cur-CS: curcumin-encapsulated chitosan; ND: not determined.
