Researchers studying spiders to make better glue

Spider

Spiders are most diverse species available on the planet, as almost 45,000 known species of spiders are available currently. Out of this much spider species, only 7,500 of them spin webs to catch the prey. These spiders use a special kind of biological glue to keep their food at the place until they feel hungry.



The glue used by Spiders is very remarkable and different than the glue we use. The glue used by human gets less sticky in wet environment, but the effectiveness of spider glue gets ticker in the wet environment. Due to this, researchers from the University of Akron and Virginia Polytechnic Institute have been studying different types of spiders.



Gaurav Amarpuri, one of the team members of the researchers said, “we measured the adhesion as a function of humidity and used high-speed imaging to quantify the spreading rate of the spiders’ glue droplets,” the researchers observes that the glue produced by spiders changes viscosity of the glue to capture its prey. He also added, “We discovered maximum glue adhesion at the humidity levels at which the spider usually forages, this is intuitive, but beautiful to observe in data.”



Researchers are studying the spider to change the property of glue that is used by us. The researchers are trying to improve the quality of the glue via this study.
