Figure 12From: A novel approach to fabricate silk nanofibers containing hydroxyapatite nanoparticles using a three-way stopcock connectorThe FT-IR spectra of the nanofibers obtained after electrospinning. Pristine nanofibers ( spectrum A), silk fibroin nanofibers modified with 10% HAp NPs ( spectrum B), 30% HAp NPs ( spectrum C), and 50% HAp NPs ( spectrum D).Back to article page
