Based on the properties of oppositely charged natural polysaccharides, the polyelectrolyte complexes (PECs) prepared with chitosan-related polycationic polyelectrolytes and cellulose-related polyanionic polyelectrolytes have been widely concerned for their potential applications as micro-drug-carriers for colon. However, the poor mechanical property of the PECs becomes the obstacle encountered in...
Sodium cellulose sulfate–water soluble chitosan (NaCS–WSC) microcapsules loaded with lactoferrin were fabricated with special performances using different degree of substitution (DS) of NaCS and WSC as potential micro-drug-carriers for colon. Effect of using cross-linking agent (sodium polyphosphate) and DS of NaCS on the structures and performances of microcapsules was studied. The results of laser...
