Date rape drug detector

A fluorescent sensor for the illicit drug GHB (gamma-hydroxybutyric acid,) commonly known as the date rape drug that predators are known to use to spike a potential victim's drink, has been developed by researchers in Singapore. When the sensor molecule is mixed with a sample from a beverage containing GHB, there is a visible color change that occurs within thirty seconds making it immediately obvious that a drink has been spiked. GHB is a central nervous system depressant banned in many countries but has been used criminally because it incapacitates a victim making them vulnerable to sexual or other assault.
