If you’re wearing rubber, you’re already doing something to protect yourself from sexually transmitted diseases. Good for you. But not everyone is always 100% diligent with this practice, and all it takes is one slip up with an infected partner for you to catch whatever they have. A team from Isaac Newton Academy in Illford, England have developed condoms coated in a special substance that glows in the dark in the presence of different kind of bacteria or virii. Better yet, they glow different colors for different bugs: green for chlamydia, yellow for herpes, purple for HPV and blue for syphilis. Having this knowledge early on in a relationship can help you avoid making a more serious mistake later on.
Currently it’s just a concept, but the students behind it are hopeful that they can develop the idea further into a real product.
