Closer to "mineralogy", plenty of things are both smaller and tougher (on this "support its own weight" metric) than cells or proteins with their squishy folding rules.
Even if we include things like hydroxyapatite in teeth, or even lignin, those are more like byproducts of biology than active biology itself.

I was thinking microscopic versus nanoscale. Folding something out of a flat material is probably cheaper than machining it, and if it's stronger than additively manufacturing it you have applications in medical devices and aerospace for starters.
Microscopic is unnecessary. Tessellation is already used in space and medical devices (not mentioned in this article: it's used in devices like stents). The specific fold being used here is named after an astrophysicist and has already been used in space.

> Wu was especially intrigued by the Miura-ori fold, named after its inventor, the Japanese astrophysicist Koryo Miura. Famed for its use in aeronautical engineering, the fold has been leveraged to make solar panels for spacecraft and satellites. One of its earliest space applications was in Japan’s Space Flyer Unit, a satellite launched in 1995.
