An assay for Staphylococcus aureus based on a self-catalytic ampicillin–metal (Fe3+)-organic gels–H2O2 chemiluminescence system with near-zero background noise

A self-catalytic ampicillin-metal (Fe3+)-organic gels (AMP-MOGs (Fe))-H2O2 CL system, which is not influenced by transition metal ions, was studied. A method for CL detection of Staphylococcus aureus (S. aureus) based on the AMP-MOGs (Fe)-H2O2 CL system was achieved. A superior detection limit of 31 CFU mL-1 toward S. aureus was obtained with near-zero background noise.
