New Procedure From Graz Detects Tiny Pollutants in Liquid

Graz researchers detect tiny particles in liquids - with a new high-tech method. The findings could make medicines and cosmetics safer. They are invisible but sometimes extremely dangerous: nano particles in liquids such as eye drops or infusions. They can trigger irritations, although they are up to 10,000 times thinner than a hair. Now a team of Graz physicists have succeeded in reliably making these tiny troublemakers visible, with a new tech…
