The drug is made from seaweed and clay nanoparticles, when injected into the area near the wound will activate the coagulation mechanism in place.
According to Science Daily, scientists at Texas A&M University in the United States have invented an ambulance that works to stop bleeding within 3 minutes. This research has just been published in Acta Biomaterialia.

Dr. Akhilesh K. Gaharwar, a member of the research team, said the main ingredient of the drug is k-carrageenan derived from a type of red algae . When combined with clay nanoparticles , it forms a hydrogel. A highly absorbable compound forms a frame, like a gauze that clots blood and seal the wound.
"The solution works to stop bleeding and first aid to internal wounds. The drug is inserted into the wound by using minimally invasive methods, accelerating the process of natural blood clotting" , Dr. Gaharwar said.
When tested on animal cells and human tissue in the laboratory, the team found improvements in tissue regeneration and injury recovery. In addition, nanoparticles can also transfer drugs to injured areas and slowly release to the body when necessary.
The drug has not been tested on human wounds. Researchers are still continuing to improve to soon bring this ambulance solution into the pharmaceutical stockpile of hospitals.
