Starch-based material to stop rapid blood loss

Scientists from the Institute of Nano Science and Technology (INST), an autonomous institute under the Department of Science & Technology, have developed a starch-based ‘hemostat’ material that concentrates the natural clotting factors in blood by physically absorbing excess fluid.

About the product:

  • The biodegradable micro particles that combine to form a gel on a wound offer significant improvements over existing alternatives.
  • The product has increased absorption capacity, improved absorption, inexpensive, biocompatible as well as biodegradable. 

Significance:

  • It is a versatile, potentially life-saving, and inexpensive product that would be a more realistic solution for lower-income economies worldwide.
  • Hemostat materials absorb excel fluid by concentrating the natural clotting factors in the blood that are critical for stopping the blood flow; however, the bleeding can restart when non-biodegradable materials are removed.
  • By chemically modifying natural starch to form micro-particles, researchers have combined the advantages of biocompatibility and biodegradability with a five- to ten-fold increase in fluid absorption and much-improved adhesion.
