- •
ATP imaging by a pH image sensor with an enzyme membrane was demonstrated.
- •
The homogeneity of the output was improved by our proposed mixed layer membrane.
- •
The detection limit of the sensor was 100 M ATP for the mixed layer method.
- •
The main factor causing the output distribution was suggested based on a statistical analysis.
