Sundew plants (Drosera) capture insects using tiny drops of a viscoelastic fluid. Researchers have used simple capillary thinning microrheometry to study the rheology and non-Newtonian flow behaviour of these mucilage drops. They have provided new insight into the ‘capture mechanism’ of the sundew plant, also suggesting that this biofluid could be a model material for processing biodegradable fibers.
