Abstract
The chemiluminescence (CL) intensity of the luminol--KIO.sub.4 system is strongly enhanced by addition of zinc sulfide nanoparticles (ZnS-NPs) capped with 3-mercaptopropionic acid. On injection of fluoroquinolones into the luminol--KIO.sub.4--ZnS--NP system, CL intensity is substantially increased. The CL emission peaks at 430 nm, thus indicating that the luminophore is 3-aminophthalate. The enhancement effect is attributed to a catalytic effect of the ZnS-NPs, which is assumed to accelerate the electron transfer process and to facilitate radical generation. Based on theses findings, a sensitive CL assay was developed for several fluoroquinolones.
