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.
As one example, in the brown layer
there's a certain type of cell
called a Langerhans cell --
every square millimeter of our body
is jammed full of those Langerhans cells,
those immune cells, and
there's others shown as well
that we haven't stained in this image.
But you can immediately see that the Nanopatch
achieves that penetration indeed.
We target thousands upon thousands
of these particular cells
just residing within a hair's width
of the surface of the skin.
Now, as the guy that's invented
this thing and designed it to do that,
I found that exciting. But so what?
So what if you've targeted cells?
In the world of vaccines, what does that mean?
The world of vaccines is getting better.
It's getting more systematic.
