Breathalyzer detects lung cancerBreathalyzers have done a lot of good ever since they were invented. They have taken many drunk drivers off the roads for one thing. Well, now they are ready to help out in a whole new way thanks to some scientists in Israel, who are working on a breathalyzer that they think can detect lung cancer.

Similar tests already exist, but require a pretreatment of the breath, which adds time to the procedure and money. The Israeli breathalyzer doesn’t need any pretreatments. The team conducted a study, with 56 healthy volunteers and 40 people who were known to have lung cancer. They were tested by the breathalyzer, using a sensor that consists of nine gold nanoparticle chemiresistors.
