Mosquitoes, the thirsty little bloodsuckers, are. As the carrier of some particularly nasty diseases, the researchers found themselves in a seemingly endless quest to repel them
"Mosquitoes are important vectors for diseases around the world and there is great interest in non-chemical protection against mosquito bites," says researcher Robert Hurt, a professor of engineering at Brown. Some clothing that is already available for purchase is infused with insect permethrin and promises to repel mosquitoes and ticks.
To test graphene, volunteers hammer their hands into a mosquito enclosure with a small patch of skin. Those who had the luck of their hand covered with graphene received no bites. The mosquitoes are bred in a laboratory so that brave test subjects do not have to worry about disease.
"With graphene, mosquitoes have not even landed on a skin patch," says lead author Cynthia Castillo, Ph.D. student at Brown. "They just didn't care."
