Condoms have a 15 percent failure
rate. Also, they do not completely protect against sexually transmitted
diseases (STDs). However, when researchers at the University of Manitoba soaked
condoms in a solution of microscopic silver nanoparticles, the condoms seemed
to kill all HIV and herpes viruses in lab experiments.
Silver has been known to have
disinfectant powers, but its effectiveness was not reliable. According to Dr.
Xiaojian Yao, lead author of the study, when silver was used in a nanoparticle
form, it seemed to become more effective at fighting off bacteria and viruses.
The small size of the nanoparticles also enabled the researchers to place them
on a polyurethane condom without changing its size or shape. The researchers do
not know exactly how the silver nanoparticles neutralize HIV and other viruses.
Dr. Yao added that the silver
nanoparticles do not cause inflammation. Currently, there are condoms treated
with the antimicrobial called Nonoxynol-9, but these can cause inflammation and
genital ulcers, which may make infection more likely. Also Dr. Yao noted that
the treated condoms are quickly discarded, so that the potentially toxic metal
does not remain in users’ bodies. Another consideration is that discarded
nanosilver-treated condoms could prevent infecting anyone who finds and touches
them.
