Effect of different initial concentrations of OVA in chitosan-TPP nanoparticles on particle size, PDI, and zeta potential. Each value is the mean of three independent measurements (n = 3 ± SD).
| Initial OVA Concentration (% w/v) |
Particle Size (± SD) (nm) |
Zeta Potential (± SD) (mV) |
PDI (± SD) |
