Fig. 1From: Nerve growth factor-chondroitin sulfate/hydroxyapatite-coating composite implant induces early osseointegration and nerve regeneration of peri-implant tissues in Beagle dogsThe surface topography, surface adhesion, and ingredients were identified in HA and NGF-CS/HA coatings. a The surface topography was observed by applying SEM in HA (n = 3) and NGF-CS/HA (n = 3) coatings. Magnification, × 2000; magnification, × 10000. b The scratch in NGF-CS/HA composite coatings were observed by SEM. c The ingredients were analyzed through XRD spectrums using the Origin7.0 software in HA (n = 3) and NGF-CS/HA (n = 3) coatingsBack to article page
