Forensic use of tandem mass-spectroscopy detects links between banknotes and drugs

01.07.2005


Research published in this month’s edition of the journal Rapid Communications in Mass Spectrometry, describes a method that can detect a pattern of contamination on banknotes from drug related crime that is different from the pattern seen in general circulation. The process is significantly faster than other previous methods.



“People involved in drug-trafficking are not always involved in handling illicit drugs, but they may possess cash that has been held by others who come into contact with drugs, so finding traces of drugs on an unusually high proportion of bank notes is another piece of evidence that could help guide a police investigation, or be used in court,” says co-author Karl Ebejer.

Work by the same group has shown that traces of cocaine may be found on a majority of banknotes. In the present study Ebejer and his team looked for the chemical diacetylmorphine (DAM), which was found to be present on around 1 in 50 notes. DAM is the major active component of illicit heroin and the most characteristic marker for that drug.


Mass spectrometry determines the chemical nature of a compound even if there is only a minute sample. In Ebejer’s process, banknotes recovered during police raids were heated to 285 oC causing chemicals to vaporise. The vapours were sucked into the detector and the chemicals smashed into fragments. One of the features of mass spectrometry is that each chemical reliably produces a unique set of fragments. The detector then looked for two particular fragments.

Finding both of these on a bank note showed that the note was contaminated with DAM. Finding lots of contaminated bank notes in a bundle indicates that the money had recently been in contact with heroin and is, therefore, unlikely to have come from general circulation.

“The association doesn’t prove guilt, but cries out for an explanation,” says Ebejer. “If a defendant can offer no reasonable explanation as to why they possess a large quantity of cash, and why this cash is highly contaminated with heroin a jury must draw its own conclusions.”

Im Focus: Light-induced superconductivity under high pressure

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.

Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
