Erratum: Gascon S.; et al. Characterization and Mathematical Modeling of Alginate/Chitosan-Based Nanoparticles Releasing the Chemokine CXCL12 to Attract Glioblastoma Cells. Pharmaceutics 2020, 12, 356

The authors wish to make the following correction to this paper [1]: In the Materials and Methods Section, there is a missing term (r²) in Equation (3), which depicts Fick’s second law of diffusion for spherical coordinates in the radial dimension assuming a constant diffusion coefficient. The equation should have been written as follows:

$$\frac{\partial C_{CXCL12}}{\partial t}=\frac{D_{eff}}{r^2}\left[\frac{\partial }{\partial r}\left(r^2\frac{\partial C_{CXCL12}}{\partial r}\right)\right]$$
