Much forensic research focuses on increasing speed and reducing sample preparation. High surface area nanogold was generated electrochemically and functionalized using alkanthiol self-assembled monolayers. The functionalized nano gold was used to extract trace amounts of drugs and explosives in complex matrices such as river water and blood. The extracted compounds were rapidly identified using Direct Analysis in Real Time (DART) tandem mass spectrometry. Preliminary data suggest that nanoporous gold can meet or exceed the detection limits of commercial SPME fibers.
