Rapid Tox-Based Wearable Sensing Badge for Solid Aerosol and Contact Exposure to Fentanyls

Nano Terra proposes to develop a low-cost and wearable detector badge that quickly and selec-tively alerts the user to the presence of solid fentanyl aerosols with an audible and visual alert. Current commercial fentanyl and opioid detectors are bulky and costly and have unsuitably-high limits of detection. Nano Terra will leverage their expertise in ultra-sensitive dosimetric detection of threat agents to advance their existing highly-selective opioid sensor for use in a compact wearable badge. The proposed system will be unobtrusive and inexpensive, while offering the necessary high sensitivity, high selectivity (distinguishes amongst fentanyl analogs and cutting agents), and rapid response time needed for the requirements of law enforcement and first responders. We will also develop and integrate a proof-of-concept toxicity-based sensor for opioids in which sensors are formulated to provide a real-time assessment of the effective human toxicity of operational environments containing multiple opioid species whose concentration or identity may not be known.
