To makes some experiments work (i.e. like FISH [0]), one needs formamide (although there are alternatives). Kapton [1] turned out to be one of the very few polymers to be able to withstand it, and also ethanol. I found out is was used for solar sails as well [2] (as original PDF, url is not working atm).<p>If we can read the article again, I bet it will come up.<p>[0] <a href="https://www.cancerresearchuk.org/about-cancer/tests-and-scans/fish" rel="nofollow">https://www.cancerresearchuk.org/about-cancer/tests-and-scan...</a><p>[1] <a href="https://en.wikipedia.org/wiki/Kapton" rel="nofollow">https://en.wikipedia.org/wiki/Kapton</a><p>[2] <a href="https://ntrs.nasa.gov/citations/20200002699" rel="nofollow">https://ntrs.nasa.gov/citations/20200002699</a>
