The detection of Escherichia coli (E. coli) with the pH sensitive hydrogel nanofiber-light addressable potentiometric sensor (NF-LAPS)

- E. coli cells are detected through a Light Addressable Potentiometric Sensor.
- Hydrogel nanofibers are used as the pH sensitive layer.
- Sugar fermentation is the basis of the sensing mechanism.
- The sensor is selective towards E. coli using d-mannose binding.
- The limit of detection is calculated to be 20 CFU/ml.
