A recent study conducted by the Swedish Defence Research Agency evaluated the performance of Surface-Enhanced Raman Scattering (SERS) for the detection of nerve agents in complex fluids. The researchers tested the detection of two nerve agents, Tabun and VX, in contact lens solution and a caffeine-based eye serum. They found that Tabun detection was successful in both media, with a practical limit of detection (LOD) ranging from 7-9 ppm in contact lens liquid and 10.2 ppm in eye serum. VX detection was more challenging and was only achieved in contact lens solution, with a practical LOD ranging from 0.6-5 ppm. These findings demonstrate the feasibility of using SERS for on-field detection of nerve agents in suspected chemical threat situations. [Extracted from the article] |
