Comparisons of the cell viability IC50 of curcumin, SCNP, and CSCNP in Hep G2 cells while stored in water for 80 days (μg/mL).
| Sample Name | Storage at 0 Day | Storage after 80 Days | Efficiency a (%) |
|---|---|---|---|
| Curcumin | 72 | 251 | 28.9 |
| CSCNP | 111 | 127 | 87.4 |
| SCNP | 140 | 166 | 84.3 |
a Formula = 1/(Storage after 80 days IC50/Storage at 0 day IC50) × 100. SCNP: silica-encapsulated curcumin nanoparticles; CSCNP: chitosan with silica co-encapsulated curcumin nanoparticles.
