A team of researchers from Innsbruck discovered the model for the development of a biological superglue at the Adriatic Sea. The one millimetre small flatworm called Macrostomum lignano can adhere to the sea water several times a second and dissolve again, explains project head and zoologist Peter Ladurner. Such biological adhesives have one major advantage: they are non-toxic and therefore well tolerated in the human body, for example to close cuts or surgical wounds.
