Scientists have long been interested in cellular nanodiscs, tiny particles made from natural cell membranes that mimic many of the functions of living cells. While previous studies demonstrated the therapeutic potential of nanodiscs for drug delivery, detoxification and vaccines, one fundamental question remained unanswered: How does size influence how well they work? https://phys.org/news/2026-10-supercomputer-reveals-size-future-nanomedicine.html Bio & Medicine Tue, 20 Oct 2026 16:20:05 EDT news711718502 Scientists have long explored the idea of using insects as our agents in the field in places where humans won't fit or survive.
