The Molecular Condom - vaginal gel releases Anti-HIV drug when exposed to semen

The lab experiments were designed to make it difficult for the molecular condom to release simulated drugs, Kiser says. Inside a woman, the gel would be much thinner than in the lab tests, so antiviral drugs "would all be released in just a few minutes."

Kiser hopes to incorporate experimental anti-AIDS drugs known as entry inhibitors into the molecular condom.
