To airport security personnel, an opaque plastic bottle is a dangerous mystery: Does it carry shampoo or explosives? Now researchers have developed a method that uses Raman spectroscopy to detect and identify concealed hazardous materials (Anal. Chem., DOI: 10.1021/ac2018102).

Current methods for identifying explosives are either invasive, like digging through a passenger’s luggage, or require time-consuming sample preparation. X-ray imaging can hint at dangers but doesn’t provide chemical specifics.

But Raman spectroscopy can give . . .
