Pathogenic bacteria cause disease outbreaks and threaten human health, prompting the research on advanced detection assays. Herein, we developed a selective mol. imprinted aptasensor for sensitive and prompt quantitation of Staphylococcus aureus (S. aureus) bacteria. The aptasensor was constructed by immobilization of aptamer on gold nanoparticles modified magnetic nanoparticles (apt-AuNPs@ Fe3O4). A functional monomer (o-phenylenediamine, o-phen) was electro-polymerized on the surface of the as-synthesized nanocomposite in the presence of a template (S. aureus). After removing S. aureus, the formed imprinted sites were available to extract pathogenic bacteria from complicated matrixes. The surface morphol. of the as-fabricated nanocomposites was characterized using different spectroscopic and electrochem. methods. Moreover, we thoroughly evaluated factors affecting the synthesis and determination procedures. The mol. imprinted aptasensor exhibited a wide linear range of 101-107 CFU mL-1 with a Limit of Detection, LOD (signal to noise = 3) of 1 CFU mL-1. The aptasensor detected S. aureus in milk, conduit water, and apple juice samples with good recoveries % and satisfactory relative standard deviations (RSDs %) values.
