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

Abstract

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.
