  • Researchers make injectable bandages to stop bleeding.
  • The bandage works inside deep wounds and cavities.
  • It helps blood form a clot quickly at wounds.
  • The dressing changes to a foam in the body.
  • The materials are tiny particles from clay-like sources.
  • Designers made the particles safer and synthetic.
  • A main problem is particles washing away in blood.
  • Engineers made two ways to keep particles inside.
  • One way expands to fill and seal the wound.
  • The other way makes a tight plug to stop flow.
