Peripheral nerve injuries (e.g. brachial plexus injury, peroneal nerve injury etc.) constitute a major proportion of nervous system diseases, which lead to neuron loss and/or neurite damage. For repairing large injuries (typically >20 mm), autologous nerve graft is the golden standard. But this therapy might be hindered by several limitations including higher risk of infection and extra pain during multiple surgeries, functional loss and limited availability of the donor nerve etc. During his/her studies, Zhongyang developed novel 3D bioscaffolds for constructing artificial nerve guidance conduit (NGCs), as substitute for the autologous nerve graft. By introducing well-defined non-biochemical factors, the neural regeneration on the scaffolds is guided and accelerated along specific direction under remote light-irradiation. Zhongyang further explored how the scaffolds can be assembled into NGCs for clinical application.


The new research findings contribute to the design of efficient NGCs for repairing peripheral nerve injuries. The combination of commonly used biochemical/cellular therapy and proposed non-biochemical factors gives great potential for promoting the regeneration efficiency.

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Science and Technology, Aarhus University.
