Abstract

The mucoadhesive properties of chitosan is suitable for extending the residence time of chitosan microparticles in the small intestine and colon. Microparticles prepared using the lowest molecular weight chitosan (62 kDa) showed the highest mucin adsorption of 55-84% and the highest zeta potential of +35.1 mV. Alginate-modified chitosan microparticles (chitosan to alginate mass ratio of 1:0.25) also showed good mucoadhesive properties with 51-79% mucin adsorption and zeta potential of +31.1 mV. The results show that the negatively charged alginate would disrupt the electrostatic interaction between the positively charged chitosan with the negatively charged mucin, and, a higher molecular weight chitosan with lower degree of deacetylation, will have a weaker interaction with mucin.
