False-colour SEM of a human blood clot
False-colour scanning electron micrograph (SEM) of a human blood clot (thrombus), showing strands of fibrin around red blood cells. Blood clots or thrombi form inside blood vessels when there is a defect in the normal haemostatic mechanism. A thrombus composed of red blood cells trapped in a network of fibrin stands is typically formed in areas of stasis (no blood flow) and is known as a coagulation thrombus. Such thrombi are commonly formed in the legs of patients confined to bed in hospital. They may be treated with drugs that interfere with fibrin formation (anticoagulants) or with fibrinolytic drugs that digest fibrin. Mag: x3, 000 at 35mm, x6, 000 at 6x7cm size. RBCs coloured light blue, fibrin pink

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph (SEM) of a human blood clot, providing an intricate view into the complex world within our veins. The image reveals delicate strands of fibrin enveloping vibrant red blood cells, offering a glimpse into the formation and composition of thrombi. Blood clots or thrombi emerge when there is an anomaly in the normal haemostatic mechanism, causing them to form inside blood vessels. In this particular case, we witness a coagulation thrombus composed of red blood cells trapped within a network of fibrin stands. These types of clots typically manifest in areas where blood flow is stagnant, such as the legs of bedridden patients in hospitals. The scientific community has developed various treatments for these potentially harmful formations. Anticoagulants are drugs that interfere with fibrin formation and can be administered to counteract their development. Additionally, fibrinolytic drugs aid in digesting existing fibrin structures. With its magnification at 3,000 times for 35mm prints and 6,000 times for larger 6x7cm prints, this SEM image offers unprecedented detail on the microscopic level. The light blue hue applied to red blood cells contrasts beautifully with the pink shade assigned to fibrin strands—enhancing both aesthetic appeal and scientific clarity. This remarkable photograph from Science Photo Library provides valuable insights into the process behind clotting while highlighting key elements such as erythrocytes (red blood cells), fibrin networks
