Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

open access: yesAdvanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.
