Figure 7. Biocompatibility testing of the hybrid material.
(a) Densely spread SH-SY5Y cells sitting on the primary polymer of a hybrid release sample after 24 h exposure. Cells were able to incorporate passively released Fluorescein from the sample and are thus brightly fluorescent. (b) SEM imaging of the cells shown in (a) at 3000× magnification showing network formation and good integration with the polymer surface.
