Abstract/OtherAbstract:
Chromium oxide (Cr(2)O(3)) nanoparticles were found to greatly enhance the chemiluminescence (CL) of the luminol-hydrogen peroxide (H(2)O(2)) system. A novel microarray CL method was originally developed for the detection of triacetone triperoxide (TATP). The novel CL method was based on the outstanding catalytic effect of a Cr(2)O(3) nanoparticle array on the CL reaction between lower concentrations of luminol and H(2)O(2), which come from hydrolysis of TATP vapor. The calibration curve of H(2)O(2) was linear over a range of 1.0 × 10(-8) to 3.0 × 10(-5) M with a detection limit of 1.6 × 10(-9) M (R(2) = 0.9992, n = 12). The CL method has the advantages of being sensitive, selective, simple, time-saving, high-throughput, and shows good reproducibility. Therefore, these merits would make it easily popular.
