Accelerated Neurite Outgrowth and Neurogenesis of PC12 Cells on an Fe-doped TiO₂ Nanorod Film Triggered by Visible Light

Acceleration of neurite outgrowth and neuronal differentiation of neural cells are critical for effective neural tissue regeneration. In addition to biochemical cues, biomaterials have proven to be a valuable tool for engineering neural cellular physiological processes. However, strategies with convenient potential spatiotemporal control are still desirable. We here design a novel Fe-doped TiO2 nanorod film using hemoglobin as the Fe source to...
