简介：
Overview
This study presents a novel protocol for designing and fabricating nanostructured porous silicon (PSi) films that serve as degradable carriers for nerve growth factor (NGF). The performance of these NGF-loaded PSi carriers is evaluated through neuronal differentiation and outgrowth of PC12 cells and mice dorsal root ganglion (DRG) neurons.
