Many of the products currently used work best on flat wounds.
They can be difficult to use on deep or irregular injuries, and some are sensitive to heat and moisture, according to Science Daily.
Researchers have therefore developed a powder that can adapt to different types of wounds.
The powder can also be stored for at least two years without losing its effectiveness, even in hot and humid conditions.

Different trials
The powder is made from naturally derived materials. When it comes into contact with blood, it quickly forms a gel that seals the wound.
According to the scientific study published in Advanced Functional Materials, laboratory tests showed that the material is gentle on blood cells and has antibacterial properties.
Animal studies also showed faster wound healing and reduced blood loss compared with existing products.
Can stop bleeding in one second
In the study, the powder was able to stop severe bleeding in about one second by rapidly forming a protective gel over the wound.
