文摘
- •
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.
