Australian scientists create methanol breathalyser

Technology Jun 11, 2025

Researchers at the University of Adelaide have created a simple breathalyzer that can quickly detect even tiny amounts of methanol in drinks or on your breath—down to 50 parts per billion. It works using affordable materials like graphene and doesn't need fancy equipment, so it could be made widely available.

Could help prevent methanol poisoning

Methanol poisoning is a serious problem in parts of Asia and the Mediterranean, where safe testing isn't always possible. This pocket-sized device could help people—especially travelers and locals—avoid contaminated drinks and stay safe. Its low cost and easy use mean it has real potential to save lives where it's needed most.
