OPH displayed on the surface of Escherichia coli with excellent enzyme activity and stability.
- •
Sensitive electrochemical microbial biosensor for p-nitrophenyl OPs was developed with ordered mesoporous carbons and OPH-bacteria.
- •
The amperometric biosensor was capable of detecting trace p-nitrophenyl OPs with high specificity.
