True, in addition to things like diatoms making silicon structures, magnetotactic bacteria make iron containing metallic structures to detect magnetic fields. It is in principle possible to both recycle and manufacture metal and silicon objects biologically with precise control over 3D structure... but a lot further off from making carbon based small molecules and polymers.

Pedantry: I love that HN has at least one person who's attempted to culture magnetotactics: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

Haha. Pedantry for future diyrs

You can start easier today (thanks thoughtful USian industry!) from, otc https://www.himedialabs.com/us/m643a-mineral-modified-glutam...

Following, e.g. (thanks academia!) https://www.researchgate.net/publication/46007644_Enhancemen...

Also note they are better thought of as anaerobic.

Also diyrs, if you're to wean off the Man, keep detailed notes (or at least back up your pdfs on tape)!

Source: have tried basic MSGM "at home" for easier anaerobes, reasonably successful

Found this, also seems diyable, not chips, but li batt anodes from beachsand (thanks the lowest end of springer-demia!) https://www.nature.com/articles/srep05623
