Scientists of Indian origin at the Department of Biomedical Engineering at the Texas A&M University, have developed an injectable bandage made from seaweed-derived gel, that can stop internal bleeding. This bandage will promote wound healing.
The researchers claim that the self-administering injectable bandage can not only control excessive blood loss from road accidents but also reduce internal bleeding, hence preventing death from blood loss. This injectable bandage has been designed using kappa-carrageenan found in seaweed. These injectable hydrogels are like 3-D jelly-like water-swollen polymer networks that simulate the structure of human tissues.
These hydrogels, when mixed with clay-based nanoparticles, produce an injectable gelatin that leads plasma protein and platelets to form blood adsorption on the gel surface, thus accelerating the clotting of blood.
“These biomaterials can be introduced into a wound site using minimally invasive approaches to promote a natural clotting cascade and initiate wound healing response after hemostasis (the process to stop bleeding),” said Dr. Akhilesh K. Gaharwar, assistant professor in the Department of Biomedical Engineering at Texas A&M University.
The study has been published in the journal Acta Biomateriali.
The study is being regarded as a remarkable addition to the achievements in nanotechnology.
“Many people die in road accidents due to internal bleeding from lack of timely medical aid, this innovation will help address the lacunae,” said Manish Goel, CEO, i3 Nanotec LLC & ICube Nanotec India.
“A more conducive environment for academia-industry partnerships and incubation space for young scientists will undoubtedly foster such and many more innovations. It is disheartening to see so many young researchers migrate to IT and finance when nanotechnology has the potential of being lucrative while contributing to the society,“ he said.
