It was found that silver nanoparticles could strongly enhance the chemiluminescence (CL) of the luminol-KIO₄ system in the presence of Co²⁺. The most intensive CL signals were obtained with silver nanoparticles in diameter of 22 nm. The studies of UV-visible spectra and CL spectra were carried out to explore the possible CL enhancement mechanism. Moreover, the influences of 17 amino acids and 25 organic compounds on the luminol-KIO4-Co²⁺-Ag NPs CL system were studied by a flow injection procedure, which led to an effective method to detect these compounds.
