Imagine being blindfolded, sent into a large (dark) room filled with obstacles and challenged to find an item, but you don’t know what that item is, and you have never seen it before. Then you must do the same again the next day, but you are looking for a different item, and it will be in a different place. The phrase fumbling around in the dark comes to mind!
Well, this is what it often feels like for forensic toxicologists trying to keep up with the unpredictable minefield of designer drugs — novel psychoactive substances (NPS).
NPS are synthetic chemicals, whether legal or illegal, closely related to known psychoactive compounds but with slightly altered composition. Not only does this make them difficult to recognize in routine screening, the fact that they are continually evolving – to evade regulation and defy law enforcement efforts — leaves drug screening labs in the dark on what compounds to target.
As if things aren’t tough enough, labs often receive wide varieties of sample types, ranging from blood and urine to hair and oral fluids, with complex biological components and challenging matrices. But it doesn’t stop there, some of these drugs are so potent that users only take a tiny amount, so the drug concentration is very low.
Fumbling around in the dark? Definitely! So, let’s remove the blindfold and shed some light on the matter.
Traditionally drug tests employ a range of targeted methods, and LC-MS/MS is recognized as one of the most efficient and reliable techniques available. The challenge is that these methods can only analyze known substances, limiting drug detection to compounds found on lists of pre-characterized analytes. In other words, if it’s not on the list, it won’t be seen.
How can toxicologists tackle the challenge of never-before-seen drugs? They need a screening tool that can detect trace amounts of unusual components in complex biological samples, even without any prior knowledge of their structural identities. This is the equivalent to removing the blindfold, turning the lights on, putting the obstacles aside and placing the item on a pedestal.
When our researchers here at SCIEX set out to do something, they don’t stop until they get there. As the opioid epidemic becomes the center of the drug overdose crisis, our team sought to develop a non-targeted screening workflow to screen novel fentanyl and its analogs in forensic biological samples.

It is no secret that (bio)pharmaceutical research and development is complex, both scientific and regulatory processes. Here is an overview of just some of the ways SCIEX is working to support these challenges.
In a recent webinar, available on demand, scientists Luiza Chrojan and Ryan Hylands from Pharmaron, provided insights into the deployment of capillary gel electrophoresis (CGE) within cell and gene therapy. Luiza and Ryan shared purity data on plasmids used for adeno-associated virus (AAV) manufacturing and data on AAV genome integrity, viral protein (VP) purity and VP ratios using the BioPhase 8800 system.
Last year, Technology Networks hosted two webinars that featured groundbreaking research utilizing SWATH DIA (data-independent acquisition) for exposomics and metabolomics. Researchers Dr. Vinicius Verri Hernandes from the University of Vienna and Dr. Cristina Balcells from Imperial College London (ICL) demonstrated how a DIA approach can be successfully implemented in small molecule analysis using the ZenoTOF 7600 system. Their innovative approaches highlight the potential of SWATH DIA to enhance the detection and analysis of chemical exposures and metabolites, paving the way for new insights into environmental health and disease mechanisms.
