Abstract During the period of 12/19/12 02/02/13 of Contract No. W911NF-13-C- 0017 we performed the following. We developed a ROC (Receiver Operator Characteristic) curve for benzenethiol (BT) on a polyvinylidene difluoride (PVDF) substrate coated with gold nanoparticles (iFyber substrate). The ROC curve indicates detection levels around 2 x 10-8 ppm of the CWA agent simulant. This is approximately 200x above the target detection level in air. The difficulty and pathway to improved detection is discussed.
