Abstract
A new method of modification for alginate-chitosan microcapsules with gold nanoparticles was reported. The gold-alginate-chitosan microcapsules were prepared with gold nanoparticles solutions. The optimum conditions of reactions and the particle size distributions of the gold-alginate-chitosan microcapsules were investigated. The value of pH=5.0 and reaction time of 120 minutes for reaction were chosen. The average diameters of the gold-alginate-chitosan microcapsules prepared respectively with citrate-stabilised gold nanoparticles and acrylate-stabilised gold ones were 216.686μm and 196.850 μm.
