Paper electrochemical devices for bacterial analysis

Background- Bacterial analysis in the field is complex and often imprecise. It is therefore difficult to detect and identify a specific strain in a timely manner, which complicates the choice of an optimal treatment regimen. This is a critical issue and bacterial infection are taking an increasing toll on the population and the health services. Having access to a widely disseminated, easy-to-use and user-friendly device would be a clear asset in this task.

Objective- The purpose of the project is to design a paper-based device for the sampling and detection of bacteria in unprepared samples. The motivation for using paper as a chip substrate are its low cost, its high availability and its capillary action that can be used to sample liquids passively. The bacterial detection will be completed using electrochemical methods with nanofunctionalized electrodes. Important aspects of the device will be i- passive sampling, ii- on board detection and iii- encapsulation of the sample in a hydrophobic layer that will limit contamination and drying of the sample.
