Plastination is a technique used to preserve biological tissues, making them durable and lifelike for educational and display purposes. This process involves replacing water and fat in the tissues with a polymer, such as silicone or epoxy resin, which hardens and maintains the original structure. The method was developed by Gunther von Hagens in the late 1970s and has since been used in various exhibitions, including the famous Body Worlds displays. Plastination allows for detailed study of anatomy without the decay associated with traditional preservation methods, making it valuable for medical education and research.
