In this study, construction of conductive and biocompatible three-dimensional nickel scaffolds (NiF) with electrodeposited chitosan (CS) for tissue engineering. The scaffolds were characterized by scanning electron microscopy (SEM), mechanical testing, water absorption, retention capacity and conductive sensitivity. Three-dimensional nickel scaffolds with electrodeposited chitosan (NiFC-n) exhibited uniformly filling structure on their surfaces and the inner structure and good mechanical property. When the versatile NiFC-n sensors were attached to different deformation, they could detect a variety of motion signals. MTT assay, Cells were stained with carboxyfluoresceinsuccinimidyl ester (CFSE) assay, apoptosis experiment and cell culture experiment results showed that NiFCn had good biocompatibility. The results indicated that the NiFC2 had a low immunogenicity, and can promote cell proliferation and support cell adhesion. This work provides a safe and feasible electrodeposition method to construct conductive and biocompatible three-dimensional nickel scaffolds with electrodeposited chitosan for tissue engineering. Therefore, NiFCn had potential application as biomaterials that may contact with real time measurement of rehabilitation for tissue engineering.
