Why haven't they made synthetic blood yet?

>>7666970
>there are no well-accepted oxygen-carrying blood substitutes

try google next time, friendo

>>7666973

we cant clone blood cells in a vat or modify them to be more efficient than a normal blood cell?

>>7666987
Not yet

>>7666970

It's already being tested.

>>7666987
we arent too far away from molecular replication
soon we can synthesize blood and other things like animal proteins

>>7666970
have you heard of immunoglobulin rejection?

>>7667628
What the fuck is molecular replication?

>>7666970
Synthetic blood already exists, and is even available on some markets (depending on where you live and your need).

Google Hemopure, its one of many blood substitutes.

ayy

>>7666970
Do you mean "synthetic" in the same way cloned organs are synthetic? Because if so, we can't?

Wow, really? That seems like the kind of thing we should have figured out by now.

>design bionanocapsules that wont be rejected in vivo
>attach multiple hemoglobin molecules or another oxygen-binding protein/domain to it

How fucking hard can it be
Cant wait to go to gradschool and after that work on shit like this

I thought they already fixed this shit but they're having a hard time getting it to coagulate properly?

Get the fuck out, autist.

why make synthetic blood when you have billions of self-replicating blood factories walking around on earth?

>>7669898
most of those "self-replicating blood factories" are dumbas who dont like the little pain of a needle.

The other problem is disease, yeah like aids hepatitis and shit

Because it's much cheaper to get people to donate

They sell your blood for hundreds of dollars per liter. Selling blood you donated is a billion dollar business.

We are very far away from that

As someone trying to basically make synthetic blood, fuck you.

What's your approach? Perfluorocarbon emulsions? Dendrimers with a crapload of porphyrins?

Personally I'd like to see artificial blood made with MOFs. If you do the math, you find that current MOFs can store as much oxygen and carbon dioxide per unit volume as the crazy diamond nano-robot artificial blood cell in pic related.

Although the kinetics of gas adsorption may not be that great(you may not be able to get it out), there may be issues with biocompatibility, MOFs aren't always stable in solution, etc.

^this guy knows his shit.

>>7670054
wrong attitude, that must be why you are failing at it

>>7669927
Or the actual problem: blood donation don't last very long.
