Abstract |
Bacterial pollution of food is one of the public health threat on global. Many kinds of pathogenic bacteria including Escherichia coli, Escherichia coli O:157, Salmonella spp., Staphylococcus can cause deadly food-related illness. To manage these risks, we had previously suggested a point-of-care paper device detecting bacteria with chromogenic substrates. Though it had showed meaningful results, low selectivity among background bacterial strains had been remained as limitation. Here, we developed a high-selective enzymatic paper sensor having four observation sections with chromogenic substrates mixture. Depending on the reaction of each substrate to target bacterium, different colors were represented on the observation regions. RGB analysis of the color reaction showed that each bacterial strain had a specific RGB pattern. This allow us to increase selectivity for background bacterial strains. The compact and easy-to-use paper sensor is expected to show potent utility in qualitative and quantitative analysis of foodborne pathogenic bacteria. |
