The cyanoacrylate molecules react with skin residue and polymerize to create a 3D matrix of the fingerprint.

氰基丙酸酯分子与皮肤残留反应并，形成指纹的 3D 矩阵。

And, yes, if you polymerize it, it becomes polypropylene.

而且，的，如果你， 就会变成丙。

It's a polymerized alkene, but the molecule itself is an alkane.

烃， 但分子本身烷烃。

The final step is activation of the protein fibrinogen to fibrin, which deposits and polymerizes to form a mesh around the platelets.

最后一步纤维蛋白原活化为纤维蛋白，集成网包绕着血小板。

The final step is activation of the protein fibrinogen (Factor I) to fibrin, which deposits and polymerizes to form a mesh around the platelets.

最后一步纤维蛋白原（因子I）激活转变为纤维蛋白，纤维蛋白沉积在血小板上，并形成网状。

But because it holds onto it's electrons so tightly, and is so satisfied in this polymerized chain, the electrons are unavailable for even minimal interactions with any other molecules.

但因为如此紧紧地抓住的电子， 并且在这个链中如此满足，电子无法与任何其他分子进行哪怕最小的相互作用。
