Each droplet has an oil core surrounded by a thin layer of butylcyanoacrylate.

每个微滴都有颗油核，周围包裹着层薄薄的氰基丙烯酸正丁。

This triggers the polymerisation of the butylcyanoacrylate into a tough plastic, which forms the outside of the capsule.

这就促使氰基丙烯酸正丁进行聚合反应转变成种坚固的塑料。这种塑料就形成了胶囊的外壳。

The capsules the researchers have come up with are made by mixing butylcyanoacrylate, a chemical found in superglue, with an oil carrying the healing compounds.

究人员创造的胶囊是通过把氰基丙烯酸正丁和有愈合功效的化合物悬浮其中的油类混合而制的。氰基丙烯酸正丁是在超强力胶中发现的种化学物质。

To overcome these problems, Dr dos Santos and Dr Mayer used special detergents that stick to the polymerised butylcyanoacrylate shell around each capsule, which stops them sticking together and protects them from the electrolytes.

为了克服这些问题， dos Santos博士 和Mayer博士使用了种特殊的去污剂，这种去污剂可以粘附在每个胶囊周围聚合氰基丙烯酸正丁的外壳上，阻止这些胶囊黏在起，并保护它们免受电解液的破坏。
