We have developed opt& sensors for pH and/or pC0, based on phase shift and modulation measurements of time-resolved fluorescence energy transfer pH-msenatrve donors and pH-sensltlve acceptors were encased m C&-permeable silicon membranes The extent of energy transfer depends on the pH-dependent abso
