University of Utah scientists have designed a “molecular condom” that women could use daily to prevent AIDS by vaginally inserting a liquid that would turn into a gel-like coating and then, when exposed to semen, return to liquid form and release an antiviral drug.

The molecular condom is part of a worldwide research effort to develop “microbicides” — drug-delivery systems such as gels, sponges or creams to prevent infection by HIV and other sexually transmitted diseases, according to an online report published in the Journal of Pharmaceutical Sciences. Microbicides will give women greater power to protect themselves from HIV, particularly in impoverished nations where AIDS is widespread or where conventional condoms are taboo.
