This paper describes the design and development of a passive wireless pH sensor tag. Under wireless interrogation, the sensor tag changes the phase of the interrogation signal according to the pH. The ...

This decrease is unexpected because the E257Q mutant represents a constitutively protonated form of this putative pH sensor and, therefore, one would anticipate an increase in pH sensitivity.
