A father who lost his daughter to methanol poisoning says he wants groundbreaking technology that traces tiny amounts of toxic chemicals through unopened bottles "in as many hands as possible".

Researchers from Adelaide University and St Andrews University in Scotland spent more than a decade developing a trio of laser techniques that can successfully trace concentrations of methanol about 10 times lower than internationally recognised safety limits.
