Abstract:
We report a handy, simple and inexpensive paper device for extremely sensitive detection of peroxide-based explosives. The sensing device fabricated using a curcumin derivative was capable of ultrafast sensing of triacetone triperoxide. The detection time was below 5 s. Moreover, the sensor retained full function under storage at ambient temperature for at least 120 days.
