Fast detection of bacterial gut pathogens on miniaturized devices: an overview

Au–Pt Coating Improved Catalytic Stability of Au@AuPt Nanoparticles for Pressure-Based Point-of-Care Detection of Escherichia coli O157:H7

“…Point-of-care testing (POCT) has emerged as a pivotal innovation, bridging the gap between the need for rapid, accessible pathogen detection, and the limitations of both traditional and advanced laboratory-based methods. These technologies enable pathogen detection at the site of patient care or in the food supply chain, providing results in a matter of minutes to hours. , Current POCT sensors usually incorporate colorimetry, , fluorescence, and electrochemical signals , as the output, making them inconvenient for resource-limited environments for lack of light source, photon detector, or electric source. In particular, pressure meters, typically simple portable devices for measuring pressure signal coupled with gas generation reactions, have garnered increasing interest in recent years. − Gas-generating reactions can be catalyzed by enzymes or nanomaterials to produce large amounts of gas, − and when in a sealed device, these obvious changes in pressure can be used as the sensor readout.…”
