Abstract
In the context of global issues concerning pathogen contamination of surface and ground waters, this pioneering study describes the fabrication of screen-printed carbon electrodes modified with polymers molecularly imprinted with lipopolysaccharide in an attempt to detect endotoxins derived from specific Gram-negative bacteria. The biosensors detected lipopolysaccharides derived from Pseudomonas Aeruginosa with high specificity, relative to control sensors, while the response to the same endotoxin derived from Escherichia coli was quite different.
