Figure 3From: Chitosan nanoparticle-based neuronal membrane sealing and neuroprotection following acrolein-induced cell injuryThe characterization of chitosan particles. TEM images of (A) chitosan nanoparticles incorporating TPP and hydralazine (Chi-TPP/Hy) and (B) chitosan nanoparticles incorporating DS and hydralazine (Chi-DS/Hy). (C) provides data on the particle size, encapsulation efficacy, and zeta potential for chitosan nanoparticle formulations. The encapsulation efficiencies showed a range from 15% to 23%, depending on the types of polyanions. Mean diameter and surface charge of particles were slightly increased upon the incorporation of hydralazine due to the presence of positively charged moieties.Back to article page
