An incisive design solution: The spider's venomous fang
(Phys.org) -- Although their armor consists of the same material as their predators fangs, flies, grasshoppers and other insects that are the usual prey of spiders have little to offer by way of defence against the spiders bite. As researchers of the Max Planck Institute of Colloids and Interfaces in Potsdam, the Max Planck Institute of Microstructure Physics in Halle and the University of Vienna have discovered, the chitin fibres in the fangs of a large Central American wandering spider are arranged and surrounded with proteins in a way that makes the material particularly rigid and thus capable of penetrating its preys cuticular armor. Thanks to the composition and structure of their materials, the fangs become optimised and reusable hypodermic needles for injecting prey with paralyzing venom. The new insights into this biological material could provide inspiration for the optimization of similar technical materials and devices.
