'Virus Sponge' Could Improve Flu Treatments, Diabetes Care, Vaccine Development

University of Maryland researchers have announced a new "virus sponge" that could aid in the treatment of, among other things, avian flu. The sponge woks similar to kidney dialysis, filtering the harmful virus from the blood. "The virus sponge is based on a technology called molecular imprinting. In molecular imprinting, researchers stamp a molecule's shape into a substance (in this case, a hydrogel--a sponge-like material). When the specific molecule filters through the hydrogel, it fits in the imprint hole and is trapped."
