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.

You don't really need the blood to be solid. Make two layers of solid brick wall, and fill the middle with layered blood bags.

UPDATE

Since you want visible blood: make "fishtank" walls of bulletproof glass, about .5m thick, and fill them with blood. For extra effect, you can pump the blood around the tank to make it swirl, or add bubbles

Bloody Paint

Why bother turning it into some kind of structural material? Just use it as the paint on literally every surface with this girl's blood. It'll be an awful color when it dries, but if dried blood still works, use it as paint. Walls, floor, ceiling, the bars on every cell. The stuff will be everywhere, radiating its effect from every direction, and it doesn't matter how weak the effect is, it's on everything.

Bonus Effect: Bloody Bullets

Coat all your ammunition with it too, every bullet, taser prong, sliver-needle, blade, and club.

Why?

Why not! Even if it's just a little bit and has a reduced effect, firing it directly into your contained escaped monsters/villains/whatever will still have a non-zero effect on their powers. Maybe the coating will even allow the bullets to penetrate those guys with the armor-skin (I mean, even if the blood-bullet has an effect radius of 1mm, that should still enough to weaken superskin at the point of impact, allowing penetration).

Sorry if I turned your plot device into a way to neuter every mutant ever, forever (just give them a blood transfusion).

This is a great idea, but I think by opting to use solid blood building material you're missing out on the opportunity to have blood piped into the prison, constantly dripping from the walls and ceilings. (Or... Why not both?)

However, as a reader I would question why you need 100% solid blood? As you put it, the radius of effect scales down linearly. Say your prison has hallways 5 meters wide. If you use 2.5% blood-content cement, the concrete alone would be good enough. Why not have a 3 meter tall cell with blood floor/ceiling tiling? Then 1.5% suffices. And if you use tiles, why would every tile need to contain blood? You could even use one tile every square meter of floor tile a blood-tile.

May I also suggest inverse square drop off? It won't make much difference on the low percent content you need, but it is inline with most physical laws. Gravity, magnetism, etc.

I would also wonder why the prison guards aren't clones of the girl. Or why they don't get blood transfusions of her cloned blood.

And humans are considerably less than 100% blood by volume or mass. Would a 100% blood solid have a larger effect radius than kind of blood/muscle/bone/flesh mixture in the girl?

I think even without the dripping ceilings or blood tiles, you could give the prison itself an artificial circulatory system. Blood in constant flux through pipes seems promising. Maybe building engineers could find a way to use blood like a refrigerant...

And as a reader I would ask "If dried blood works, why not make every building and every piece of infrastructure contain some of her blood? Or paint road stripes with dried blood?" That would do away with the super-villain threat every except Rural areas. Building new infrastructure across America just to pump blood would be a non-solution though, due to investment cost, upkeep, and the time needed to implement it.

I've heard rumors that blood was used as an ingrediant in Roman Concrete. Google: Patent US4203674

Concrete that nullified superpowers seems like a great material for a prison.

Added bonus: you can say that the prison architects got the idea from Roman sources as the Romans developed the technique to contain "Magic" prisoners...if that even fits or something.

Blood vapor

Since the other answers have covered the solids (walls of blood gel) and liquids (paint, coat everything, mix in water supply), permit me to propose another phase: blood vapor. You could have atomizers installed throughout the prison which spray fine blood into the air at regular intervals. So your inmates will stay depowered provided you maintain sufficient density of blood in the air.

Bonus:

  • Blood spray: Instead of pepper sprays, the guards walk around with blood sprays.

  • Blood-smoke bombs: You could use this idea to make blood-smoke bombs which the government can use to suppress peaceful (or violent) demonstrations by superhumans. If the government soldiers are engaged in combat with the superhumans, using these bombs will have a large area of effect and be more useful when compared to blood-coated bullets or blades as the government soldiers will be unaffected (assuming they are not superhumans).

  • Blood mines: Strategically place and prime the blood-smoke bombs (as mines) on the perimeter of the prison as a line of defense for escaping/attacking superhumans.

So if you are going for a visual effect I think it could be really neat to have the prison be covered with "veins" everywhere. Essentially it could look like a venous system that humans have. This would give a visually stunning appearance (my own personal opinion having looked at the venous system before) and give you the opportunity to weave in other elements into the prison if you so desired (say for instance the prison is a living entity or something). Of course this doesn't make it a solid but you could always make it into a solid spiderweb design if you so desired.

As an alternative, fit prisoners with collars. In movies and anime, the collars would be fitted with explosives or toxins; in your case, you can have them contain the girl's cloned blood.

This way less blood is needed compared to using it as building material or paint; it also won't stink up the place.

If the collars have very difficult to break fiberglass tubes, you can have dark red fluid sloshing around inside and retain the visual impact as well.

    $\begingroup$ I'd actually had a similar idea for those who weren't necessarily evil, but whose powers were "too dangerous" (i.e. "would break my story") - give them bracers made from the cloned blood to nullify their powers. Collars would work too. $\endgroup$

Idea 2: Dilute the blood in the water supply, if the blood is potent enough.

It could run through the pipes in the walls in all directions. The prisoners will drink, eat, shower, sweat and piss it everywhere, they'll be their own "de-powering" nodes. The effect can last a while outside the prison. If the property doesn't degrade and the water is recycled the concentration can accumulate over time.

The guards give the prisoners placebo pills posing as the neutralizing agent. They make a big deal to enforce their administration to decieve the prisoners as to the source of the agent.

How many prisoners have you got? I feel you're approaching this wrong looking for a solid.

People manage to get out of prisons. All the time, even without super powers.

The most effective prisons make it so that getting outside the walls is just the start of your escape. Stalin sent political prisoners to Siberia for a good reason - escape means freezing to death or the guards easily tracking you through the snow.

Your setup would make it too easy for prisoners to escape far enough to regain their powers, and from there, they will get to safety.

Any physical object, even one buried in the skin could be fled from by a determiend prisoner.

But you can't escape from your own blood.

Assuming the girl has O-type blood (the most common type), you can simply inject 0.0008 pints of her blood into each prisoner, every 8 weeks (blood wears out after 120 days, but we need a factor of safety as the injected blood won't be brand new). This would leave the prisoners blood 0.01% antimagic, which should have a range of 1 cm. You can't be more than 1 cm ft from your own blood, so should be safe.

Many people donate a pint every 8 weeks, so this should cover 1200 prisoners.

Get some friendly superheroes to help you test these numbers. Maybe you can go lower than 0.01% (1 cm range) if the magic source is an organ that receives bloodflow.

More than 1 pint/8 weeks may be possible with advanced medical care for the girl, and with her not performing any heavy lifting, driving etc.

Blood bags

Specifically, the fleshy kind...

Instead of just collecting the blood, you instead gather enough material to begin a cloning program; only there is no need to create proper clones, you just need some internal organs and a cardiovascular system, resulting in 'flesh bag' blood generators.

Instead of some blood based paint that would likely degrade, or changing the nature of the blood, which could destroy whatever is causing the effect, you how have a large number of living null-field generators that can be hooked up to small life support systems.

It's a different visual impact to raw blood in vials, but still a big one. It may also fit better into how power systems may work in your world. Usually, there is little to no lingering effect from a power. Your world may be different, but if not, this may be more internally consistent, than having blood somehow retain its ability when no longer part of a living creature, and not having an isolatable active ingredient producing the effect.

note: blood carrying effects e.g. vials of blood in pendants etc, is typically more common in a magical setting, where it is the ritual etc of producing the artifact, or magic cast on the blood that causes the effect, allowing it to last while also being a non-physical feature, so being unable to extract it. If magic is a superpower in your world, then you could make it a magic based power
