Three London teenagers have invented a condom that changes colour if the wearer has a sexually transmitted disease. The condoms, made from a rubber called S.T.EYE, react to various
pathogens that cause STDs, turning green for chlamydia, blue for
syphilis, yellow for herpes and purple for genital warts. The
invention was the brainchild of Dannyaal Ali, 14, Muaz Nawaz, 13 and
Chirag Shah, 14, who won first prize in Britain’s TeenTech Awards, set
up to encourage schoolchildren to pursue careers in the sciences.
Ali said: “We wanted to make something that made detecting harmful STIs
safer than ever before, so that people can take immediate action in the
privacy of their own homes without the often-scary procedures at the
doctors,” adding: “We’ve made sure we’re able to give peace of mind to
users and let people act even more responsibly than ever before.”
He
told the BBC: “Once the [bodily] fluids come into contact with the
latex, if the person does have some sort of STI, it will cause a
reaction through antibodies and antigens hanging on to each other, which
triggers an antibody reaction causing a colour change.
“We took inspiration from an HIV testing method [called Elisa] which utilises colour-changing
The boys have won £1,000 for their school, the Isaac Newton Academy,
and will meet Prince Andrew at Buckingham Palace in October.
Dr Mark
Lawton, a consultant in sexual health and HIV at Royal Liverpool
Hospital, pointed out a few potential problems, however: “To play
devil’s advocate, would it dissuade people from using condoms if they
were worried about being found out?
“Or if they were worried that
the person they were going to have sex with didn’t want to have sex with
them if they found something?”
Overall, though, he praised the teenagers for their ingenuity and awareness of STDs.
