Figure 1

Chemical structure of chitosan-thioglycolic acid conjugate (A) and transmission electron micrograph of chitosan nanoparticles following ionic crosslinking (B). Adsorption kinetics of mucin I-S with unmodified and thiolated chitosan nanoparticles (C). The value of mucin adsorbed represents the amount of mucin per 2 mg of chitosan nanoparticles. The experiments were repeated twice and results are expressed as mean ± S.D (**P < 0.01, *P < 0.05 relative to 1 h).
