There are growing studies in recent years concerning the use of different carrier materials for sustained-release and controlled-release of nerve growth factor in neuroscience research.

Results showed that amino functionalization improved carbon nanotubes-nerve growth factor complex dispersibility, reduced their toxicity to PC12 cells, and promoted PC12 cell differentiation and chick embryo dorsal root ganglion. This study has been reported in the Neural Regeneration Research (Vol. 9, No. 3, 2014).
