Ultrasensitive Impedimetric Electrochemical DNA Biosensor for Detection of Enterotoxigenic <i>Escherichia coli</i> (ETEC).

ABSTRACT: Enterotoxigenic Escherichia coli (ETEC) is a pathogenic strain of E. coli, which is transmitted via food and water, primarily causing diarrhea in children below 5. Due to similar biochemical properties, conventional culture and biochemical identification methods are unsuitable for distinguishing ETEC. Immunoassay and molecular detection are alternative techniques for detecting ETEC, which target heat-labile (LT) and heat-stable (ST) enterotoxins. However, they may require specialized equipment, and some methods may require a pre-enrichment process, making them unsuitable for rapid and on-site detection. This study designs a DNA-based electrochemical biosensor, specifically for detecting the heat-labile toxin (LT) gene of ETEC. The screen-printed electrode (SPE)
