Researchers Develop World’s First Fluorescent Sensor to Detect Common Illicit Date Rape Drug within Seconds

by National University of Singapore
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.
