Various chemical modifications of chitosan have been studied to alter their properties. This paper reported a method of modification for alginate-chitosan microcapsules with gold nanoparticles. The gold-alginate-chitosan microcapsules were prepared with gold nanoparticles solutions. Diffusion properties of the gold-alginate-chitosan and alginate-chitosan microcapsules were investigated by the permeability to Vitamin B12. And the influence of initial concentration of Vitamin B12 on permeability also was investigated in this paper. The permeability of gold-alginate-chitosan microcapsules was higher than those of before modified. And the influence of initial concentration of Vitamin B12 on permeability was paltry.
