with this old technology and the needle.
But it could be argued that the needle
is holding back our immune responses;
it's missing our immune sweet spot in the skin.
To describe this idea,
we need to take a journey through the skin,
starting with one of those projections
and applying the Nanopatch to the skin.
And we see this kind of data.
Now, this is real data --
that thing that we can see there is one projection
from the Nanopatch that's been applied to the skin
and those colors are different layers.
Now, to give you an idea of scale,
if the needle was shown here, it would be too big.
It would be 10 times bigger
than the size of that screen,
going 10 times deeper as well.
It's off the grid entirely.
You can see immediately that we
have those projections in the skin.
That red layer is a tough outer layer of dead skin,
but the brown layer and the magenta layer
are jammed full of immune cells.
