When added to condoms, microscopic nanoparticles of silver may create a powerful safety net against HIV and sexually transmitted infections (STIs), the Canadian National Post reported. Seeking to mitigate condoms’ 15-percent failure rate, and to find a long-elusive additive that can prevent STIs without causing inflammation and ulceration in the genitals as with the spermicide Nonoxynol-9, researchers from the University of Manitoba soaked condoms in a solution of silver nanoparticles and found that the treated latex sheaths killed all HIV and herpes in their lab experiments.

A test for HIV that is 10 times more sensitive and a fraction of the cost of current methods, has been developed by British scientists.
It uses nanotechnology to give a result that can be seen with the naked eye by turning a sample red or blue.
Developed by scientists at Imperial College in London, the technique offers the promise of better diagnosis and treatment in the developing world.
