For any medical reason, sometimes artificial organs are required to take place instead of the real organ in the human body. But making artificial organs, which have complicated and intricate structures, aren't easy to make and there have been many methods which have been devised but don't work as efficiently. Leon Bellan is an assistant professor of mechanical engineering at Vanderbilt University, who has been working with candy floss machines, getting them to spin out networks of tiny threads similar in size, density and complexity to the patterns formed by capillaries - the minuscule, thin-walled vessels that deliver oxygen and nutrients to cells and carry away waste. His main aim has been to make fibre networks that can be used as templates to produce the capillary systems required to create full-scale artificial organs. This research has been published in the Advanced Healthcare Materials journal. Bellan and his colleagues have been successful in using their
