Molecular condom protects from AIDS

Scientists from the University of Utah have created a "molecular condom" which prevents the AIDS virus from diffusing into vaginal tissue. Upon contact with semen the gel turns semi solid, trapping the AIDS virus in a microscopic mesh. The gel is in development for eventual use in Africa and other impoverished areas where women don’t believe they can persuade their partners to wear condoms. "We have created the first vaginal gel designed to prevent movement of the AIDS virus," says Patrick Kiser, senior author of the study. "This is unique. There’s nothing like it."
