Fig. 2From: Feasibility of a novel, synthetic, self-assembling peptide for suture-line haemostasis in cardiac surgeryContact between PuraStat® and physiological liquid such as blood causes the acidic peptide solution to approach neutral pH and be exposed to ions. This triggers self-assembly of ß-sheets and then nano-fibres within a hydrogel. The hydrogel rapidly covers the point of bleeding and provides a physical surface under which coagulation occurs to achieve haemostasis. (figure courtesy of 3-D Matrix)Back to article page
