Abstract
after 1 min. Moreover, the biosensor was capable of specifically distinguishing S. aureus from other food- and water-borne bacteria such as E. coli and Listeria using the dual mode colorimetric and electrochemical detection. The biosensor was also tested in spiked milk and water samples showing very good recovery percentages. Thus, we believe that this dual mode biosensing platform enables the easy and accurate determination of S. aureus and holds great promise for point-of-care diagnosis.
