Chromium oxide (Cr2O3) nanoparticles were found to greatly enhance the chemiluminescence (CL) of the luminol-hydrogen peroxide (H2O2) 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 Cr2O3 nanoparticle array on the CL reaction between lower concentrations of luminol and H2O2, which come from hydrolysis of TATP vapor. The calibration curve of H2O2 was linear over a range of 1.0 x 10(-8) to 3.0 x 10(-5) M with a detection limit of 1.6 x 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.
