Researchers have discovered a new way to stabilise haemoglobin, the oxygen carrier protein in the blood.
Researchers wrapped up haemoglobin with the polymer poly(acrylic) acid, protecting it from the intense heat used in sterilisation while maintaining its biological function and structure.
Poly(acrylic acid) is the same material found in disposable nappies, and is one of the most abundant synthetic polymers on the planet. The discovery may help researchers develop affordable artificial blood substitutes.
