Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot within a few minutes without sticking to the wound. The developers wanted to develop a coating for devices such as heart-lung machines or artificial heart devices but ended up developing a new superhydrophobic material. The researchers used a regular cotton bandage and coated it with a mixture of silicone and carbon nanofibres. They observed that the coated bandage clotted the blood in a few minutes. The bandage material would prevent reopening the wounds that will minimize the risk of serious infections from the hospital bacterias and would be helpful in medical aids and surgery to avoid blood loss.
