Nanofiber gel stops bleeding fast

Super quick fix for bleeding.

Last June 4th, I reported that MIT researchers used a self-assembling peptide nanofiber scaffold to repair severed brain structures in blind rodents and restore their sight. Those same researchers noticed the material's dramatic ability to stop bleeding in the brain and began testing it on a variety of other organs and tissues.

In a study published online October 10 in Nanomedicine the researchers report that the liquid controlled bleeding in rodents within 15 seconds in seven other wound types, including cuts to the spinal cord, liver [view video here] and femoral artery as well as skin punctures.

Platelets not needed

The liquid does not seem to form a conventional blood clot, the group notes. Electron microscopy turned up no sign of the platelets that would normally gather in a clot. The proteins might instead form tangles that act like hair blocking a drain, Ellis-Behnke suggests.
The gel eventually breaks down into amino acids, the building blocks of proteins, that can be used by surrounding cells for tissue repair.

This discovery has created lots of excitement, especially by surgeons. Still, they caution that extensive clinical trials are needed to make sure the materials work properly and are safe. The MIT researchers hope to see those crucial human trials within three to five years.

Wow, people should really check out this video. You first see a living liver inside some sort of animal (a lab rat I assume). Then the surgeon makes a cut into the liver and it starts to bleed. He then takes a needle and sprays some of the nano liquid over the cut and it immediately stops bleeding. Like, IMMEDIATELY! Interesting for sure.

I agree but its not for the faint of heart or those of the animal activist.

Better that animals be used for these studies if it helps man and if the are treated well and kept reasonably pain free.They should not be tortured.Man is held responsible by God for the way he treats his domestic animals. Animal families don't worry about them.They seem to heal faster than humans,don't have to take care of families as do humans and they were given for humans as food.Gen 6:9 .Humans lives are taken on a large scale in wars and other ways. Why should animals be considered more precious than man who were "created in God's image"?

Where can we get this gel?What is the cost?

Like many new nanotechnology breakthroughs this gel is not yet a product you can buy. One of the big challenges that nanotech scientist face is figuring out how to cheaply manufacture what they create in the lab. So we shall have to see how long before this new discovery finds its way into the public.
