Valproic acid-labeled chitosan nanoparticles promote recovery of neuronal injury after spinal cord injury

Figure 1. Valproic acid modified chitosan nanoparticles (VA-CN). (A) Chemical structure of VA-CN nanoparticles. (B) TEM image of VA-CN nanoparticles (Scale bar: 200 nm). (C) Sizes of VA-CN and CN nanoparticles were observed for different time points during one mouth. (D) Zeta potential of VA-CN and CN nanoparticles were detected by ZetaPlus for different time points during one mouth.
