Me:

Plus, carbon nanotubes are black, not silver.

HPMOR:

Over the next seconds, those near-invisible threads of reflected moonlight turned black.

Dammit.

Incidentally, did none of the death eaters have shields raised, or did the filaments pass through the shields?

Considering the only DE to raise shields also tried to kill LV and attempted to enlist the rest of them to join him...

The persona of LV might well have considered it a betrayal, to have their shields up around their lord. For why would you need them, if you were not plotting treachery?

Why raise shields, when they are instructed to hex Harry as soon as he raises his wand?

Wordless, quasi-invisible partial transfiguration is a power they know not, so they did not prepare for it.

Raise shields on general principles! There could be Aurors with invisibility cloaks or disillusioned nearby, enemies could suddenly appear by phoenix or some other method, there could be muggleborns with sniper rifles hidden a km away, someone could have travelled back in time to plant a bomb, one of the Death Eaters could be a traitor...

Mad-eye Moody would be disappointed.

EVER VIGILANT!

Which reminds me of something I noticed. Harry should have flooded the area with neurotoxin on general principles, because there might have been invisible Death Eaters.

Presumably shields let air through, so they probably also let nanotubes through.

Well, I don't know how shields work in this setting, but one possibility is that shields do not let anything magical through, which would stop transfigured materials. Shields do stop bullets, so... is it a matter of speed? Do shields stop fast things like bullets, but let slow things such as knives through?

If carbon nanotubes work, then wizards who are not familer with the latest muggle science could still stab each other with very thin (to the point of near invisibility) diamond blades.

The slow nanowire penetrates the shield.

I guess this is plausible.

That sounds entirely too much like Dune to me. That's enough reason for me to doubt shields work that way.

Why? I wouldn't be surprised by the inclusion of a homage to Dune.
