New technique can reveal previously undetectable bacteria in places where they aren't wanted

Scientists create graphene patterns on food and other materials as a new class of edible electronics

A team of researchers from the National University of Singapore (NUS) has developed the world’s first fluorescent sensor to identify the presence of a drug known as GHB that is commonly used to spike beverages. When the sensor is mixed with a sample of a beverage containing GHB, the mixture changes colour in less than 30 seconds, making detection of the drug fast and easy.

Richard Martel and his research team at the Department of Chemistry of the Université de Montréal have discovered a method to improve detection of the infinitely small. Their discovery is presented in the November 24 online edition of the journal Nature Photonics.

HPLC-fluorescence detection is now designated as the official analysis method for many components across various industries
