Scientists had long suspected that bacterial nanowires were pili — Latin for «hair» — which are hair - like features common on other bacteria, allowing them to adhere to surfaces and even connect to one another.

Once we were able to induce nanowire growth, we started analyzing their composition and structure, which took another year of work.
