Under these conditions, the silk fibroin and gum arabic formed into tiny oil-containing capsules.

在这些条件下，丝素蛋白和阿拉伯树胶形成微小的含油胶囊。

The crucial ingredient is silk fibroin, a protein that can be fashioned into structures that let the liquids they contain leak out slowly.

关键成分是丝素蛋白，这种蛋白质成让其所含液体缓的结构。

Dr Tariq and Dr Wang speculated that if microscopic silk fibroin capsules could be filled with lavender oil, this liquid would gradually be released.

塔里克博士和王博士推测， 如果能将薰衣草油填充到微观丝素蛋白胶囊中，这种液体就会逐渐释放出来。

Working with a team of colleagues at universities across China, the researchers created a solution of silk fibroin and gum arabic, a polymer found in the sap of acacia trees, which is used to help materials form into stable structures.

研究人员与中国各所大学的同事团队合作，创造了一种丝素蛋白和阿拉伯胶溶液，阿拉伯胶是金合欢树汁中发现的一种聚合物，用于帮助材料形成稳定的结构。
