Because they are so small, it is hoped that nanodevices will someday be able to travel through tiny capillaries and deliver oxygen to anemic tissues, remove obstructions from blood vessels and plaque from brain cells, and even hunt down and destroy viruses, bacteria, and other infectious agents.
Kuna nanoseadmed on sedavõrd pisikesed, loodetakse, et ühel päeval suudavad need läbida tillukesi kapillaare ning transportida aneemilistesse kudedesse hapnikku, eemaldada veresoontest ummistusi ja ajurakkudest naaste ning koguni avastada ja hävitada viiruseid, baktereid ning muid nakkustekitajaid.
