Fabrication and Properties of Electrospun Magnetoelectric Graphene/Fe₃O₄/Poly(lactic-co-glycolic acid) Short Nanofibers.

When used in tissue engineering, polymer nanofibers with magnetic and electrical functionality could promote the growth of tissues and cells by applying magnetic and electric stimulation. Short nanofibers with these properties, which have a high specific surface area and can be arranged through magnetic induction, have potential applications in the fields of materials and biomedical engineering. In this study, poly(lactic-co-glycolic acid) (PLGA) nanofibers with nano-Fe₃O₄ particles were subjected to electrostatic spinning to obtain superparamagnetic Fe₃O₄/PLGA nanofibers. After being processed in a homogenizer, graphene/Fe₃O₄/PLGA short nanofibers with a length of 11.90±2.03
