| 摘 要： | 分别用柠檬酸钠和丙烯酸钠做还原剂制备金纳米微粒,并分别用它们对几丁聚糖微胶囊进行化学修饰,提出了新的修饰方法,制备出新的金-海藻酸钙-几丁聚糖微胶囊(GACM).运用分光光度法对2个体系下制得的GACM的渗透性进行了测定,结果表明柠檬酸体系下制得的GACM的渗透性比丙烯酸钠体系下制得的GACM的渗透性要大. |

| Abstract: | The permeability is one of the most important properties of microcapsules.It is reported a modification for alginate-chitosan microcapsules with nanosized gold citrate or acrylate.The comparison of permeabilities for gold-alginate-chitosan microcapsules modified with nanosized gold citrate and acrylate was reported by spectrophotometry and using Vitamin B12 as penetrant.The experimental results showsed that the permeability of gold-alginate-chiosan microcapsules treated with citrate was higher than that of gold-alginate-chitosan microcapsules treated with acrylate. |
