Abstract

The development of efficient, portable, and cost-effective diagnostic tools is essential for real-time bacterial detection in healthcare, food safety, and environmental monitoring. This study presents a novel printed multicomponent paper sensor designed to detect bacterial pathogens rapidly and accurately. The sensor integrates multiple functional components, including colorimetric indicators and selective reagents, which respond to bacterial metabolites, leading to visible color changes. Using simple printing techniques, the sensor is fabricated on paper substrates, ensuring low production costs and environmental sustainability.
