Surface characterization by AFM (A–D), contact angle (E) and biocompatibility evaluation (F). A Topographical feature of osteogenic nanofibrous coated (ONFC) implant, B uncoated implant, C height profile of ONFC titanium implant and D uncoated implant. AFM analysis reveals ONFC implant have more surface area and roughness compared to uncoated titanium implant. E Water contact angle of ONFC, PCL nanofibres and (Ti) titanium implant surfaces is shown. ONFC exhibits hydrophilic features. F Resazurin assay for measuring cell viability in ONFC and PCL nanofibres. No statistical significant difference was observed between test and control confirming that ONFC is nontoxic and have biocompatible features
