Triacetone triperoxide (TATP) is relatively easy to make and has been used in various terrorist acts. Early but easy detection of TATP is highly desired. We designed a new type sensor array for H₂O₂. The unique CL sensor array was based on CeO₂ nanoparticles' membranes, which have an excellent catalytic effect on the luminol-H₂O₂ CL reaction in alkaline medium. It exhibits a linear range for the detection of H₂O₂ from 1.0¡Á10^?8 to 5.0¡Á10^?5 M (R²=0.9991) with a 1 s response time. The detection limit is 1.0¡Á10^?9 M. Notably, the present approach allows the design of CL sensor array assays in a more simple, time-saving, long-lifetime, high-throughput, and economical approach when compared with conventional CL sensor. It is conceptually different from conventional CL sensor assays. The novel sensor array has been successfully applied for the detection of TATP at the scene.
