Urinary tract infection (UTI) is a public health concern, estimated to cost billions of dollars in diagnosis and treatment every year. Consumption of cranberry has been correlated with the prevention of UTI, due to the presence of key plant metabolites called polyphenols. We fabricated functionalized screen-printed electrodes (SPEs) and tested the effectiveness of the biosensor for detecting the presence of Escherichia coli (ExPEC) in aqueous suspensions. Results indicated that thewas highly sensitive (limit of quantification of 1 CFU/mL of ExPEC), and its response was linear over the concentration range of 1–70,000 CFU/mL.
