Abstract

Abstract: In this work, a three-dimensional interwoven network composed of Van-PEG-MWCNTs was successfully constructed for the capture of Staphylococcus aureus. The capture behavior of this network against Staphylococcus aureus in simulated solution and real milk was studied. Grafting Van-PEG on carbon nanotubes endowed carbon nanotubes with activity against S taphylococcus aureus, and improved the dispersibility of carbon nanotubes in solution system at the same time, so that they can be suspended in solution uniformly and form a loofah-like three-dimensional structure, enabling the grafted complex to capture Staphylococcus aureus efficiently in the solution system, even the low-level target bacteria can also be captured. The results showed that Van-PEG-MWCNTs played a role as molecular probes that can identify and capture Staphylococcus aureus from phosphate-buffered saline solution and fresh milk samples with a LOD of 2 × 10 1 CFU/mL. This study demonstrated the potential application value of Van-PEG-MWCNTs for rapid and efficient detection of Staphylococcus aureus . Graphical abstract: Image 1
