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

氰基丙烯酸酯分子与皮肤残留反应并聚，形成指纹的 3D 矩。

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

而且，的，如果你聚它， 它就会变成聚丙烯。

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

它聚烯烃， 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.

最后一步蛋白原活化为蛋白，聚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.

最后一步蛋白原（因子I）激活转变为蛋白，蛋白沉积在血小板上，并聚形成网状。

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.

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