WebFeb 21, 2024 · The mean hydrodynamic diameters of blank LnPs and Zhubech were 90.0 ± 0.65 nm and 124.9 ± 3.2 nm, respectively. The hydrodynamic diameter of Zhubech was found to be highly stable at 4 °C and 25 °C for 30 days in solution. In vitro drug release of MFU from Zhubech formulation exhibited the Higuchi model (R 2 value = 0.95). WebApr 14, 2024 · The data suggest that the release from the hydrogel samples studied was best described by Higuchi’s model. In order to further clarify the release kinetics, Figure 9a–c shows the Higuchi’s model curves for all samples. These finding suggests that the developed hydrogel matrices are effective in controlling release via a diffusion mechanism.
