A “molecular condom” to protect women against HIV is being developed by US scientists.
The liquid formulated by a University of Utah team turns into a gel-like coating when inserted into the vagina.
Then, when exposed to semen, it returns to liquid form and releases an anti-viral drug to attack HIV.
However, the technology, featured in the Journal of Pharmaceutical Sciences, is still around five years away from being tested in humans.
[…]The Utah project is part of a worldwide research effort to develop “microbicides” – drug-delivery systems such as gels, rings, sponges or creams to prevent infection by HIV and other sexually transmitted diseases.”
And in case you have never heard of microbicides before:
The word “microbicides” refers to a range of different products that share one common characteristic: the ability to prevent the sexual transmission of HIV and other sexually transmitted infections (STIs) when applied topically. A microbicide could be produced in many forms, including gels, creams, suppositories, films, or as a sponge or ring that releases the active ingredient over time.
Keep microbicides in mind, because you are going to hear a lot of them in the future.
