Green: collagen, red: cell nuclei. (Photograph: ETH Zurich / Matthew Aronoff) - Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumours, the molecule could play a significant role in research of wound healing disorders. Collagen is the most abundant protein in the human body. It makes up a third of protein content and single strands assemble to form stable fibres that give structure to connective tissue such as skin, tendons, cartilage and bones.
