Superparamagnetic iron oxide nanoparticles (SPIONs) have been used for a variety of biomedical applications, from multimodal imaging to the mechanical activity of cells and tissues. Herein, we present fluorescently mantled carbon coated core-shell superparamagnetic iron oxide nanoparticles (FC-SPIONs) as an excellent material to promote the neuronal differentiation and neuronal network outgrowth in neural tissue engineering applications. Morphological, structural, and functional group characterizations were systematically investigated. FC-SPIONs showed superior magnetic and inherent fluorescence characteristic properties. Furthermore, FC-SPIONs interactions against neuronal PC12 cells showed promising results and deliberate their potential for significant applications in neuroengineering. Interestingly, FC-SPIONs were assessed as biocompatible and promoted the neuronal PC12 cell differentiation process. Accompanied by these results, network outgrowth and branching patterns of neuronal processes can be regulated using FC-SPIONs. Importantly, FC-SPIONs are promising due to their biocompatibility and selective affinity toward neuronal cells, paving the way for neuronal differentiation and outgrowth and neuronal therapeutics in neuroengineering applications.
