The researchers’ paper is written in such a way that any laboratory can reproduce the black-light experiment. These include changing gloves frequently, using vials and test tubes with large mouths to limit spillage when transferring material into them, and having two sets of wash bottles, one for casework and one for cleanup. This visualization experiment led the authors to suggest several steps that might minimize spread. Highly sensitive instruments are more likely to detect small amounts of drug residue in the environment, so those labs have to be extra careful about limiting their spread.
Drug dealers often mix small amounts of fentanyl into heroin and cocaine, and some labs are increasing the sensitivity of their instruments to detect those small amounts. But that has changed, and not only for reasons of workplace safety. Under everyday lights the brick looked like evidence from a drug seizure, but under ultraviolet light - also called UV or black light - it glowed a bright orange.īefore the emergence of fentanyl and other super-potent drugs, such small amounts of drug residue were not a major concern. To see how it happens, the two NIST research scientists, Edward Sisco and Matthew Staymates, fabricated a brick made of white flour mixed with a small amount of fluorescent powder. The spread of drug particles cannot be completely avoided - it is an inevitable result of the forensic analyses that crime labs must perform. Their study, recently published in Forensic Chemistry, addresses safety concerns in an age of super-potent synthetic drugs like fentanyl, which can potentially be hazardous to chemists who handle them frequently. Instead, their aim was to study the way drug particles get spread around crime labs when analysts test suspected drug evidence. When two scientists from the National Institute of Standards and Technology (NIST) brought black lights and glow powder into the Maryland State Police crime lab, they weren’t setting up a laser tag studio or nightclub.
