Researchers at Brown University have found a possible solution using graphene. The research, published in 2019, demonstrates that a graphene film on skin not only blocked mosquitoes from biting but even deterred them from landing on skin in the first place. One possible explanation is that the graphene prevented the mosquitoes from smelling prey.
