A biocompatible nanofibers modified by plasma for osteoblast growth differentiation

This work employs nitrogen plasma immersion ion implantation (PIII) to modify electrospinning polylactic acid membranes and immobilizes basic fibroblast growth factors (bFGF) by forming crosslinking bonds. The study investigates the modified membranes' surface characteristics and the stimulatory effects of crosslinked bFGF polylactic acid membranes on osteoblast and fibroblast proliferation. The PIII process occurs under low vacuum conditions and is controlled by processing time and power pulse width. The experimental results indicate that, within a 400-second N
