Is it possible to create a room-temperature solid made from 100% human blood?
One of my stories features a girl who has the passive ability to block the superpowers of anyone in a 100-meter radius. The government decides that this would be quite a nice power to have - for example, building a supervillain prison in which the villains can't use their powers. So they take a sample of the girl's blood, so they can use it to make some kind of solid material with the same properties.
Assume that the government has some kind of advanced Handwave Machine that can produce genetically-identical blood, and that the blood retains the "passive-blocking" ability, but diluting it with other substances proportionately weakens it (so for example, something that's 60% blood and 40% iron will only have a 60-metre blocking radius).
With that in mind: Is it possible to create a room-temperature solid made from 100% human blood? If not, what material(s) would you have to mix in to make this possible? What physical properties would the resultant material have? It doesn't need to be super-strong, just strong enough that it could be used in floor/wall tiles.
UPDATE: Thanks for all the amazing answers so far. A few clarifications, since the comments have been moved to chat:
- The ability is an intrinsic property of the girl's blood and can't be separated out (i.e. via centrifuge). It has to be the blood.
- Since most of the answers seem to have focused on the "supervillain prison" example, I'd like to add that that's not the only place it's used. It's also used in important buildings (government offices and the like) to deter supervillain attacks. This is also where the radius part comes in - it's preferable in those buildings to use only a few strategically-placed tiles, rather than covering every wall with blood and creeping everyone out. This shouldn't invalidate the existing prison-oriented answers, as they still work great.
