Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore ...

To address the problem of repeated calibrations and to study the effect of biofouling on the electrode–electrolyte interactions, we explore the link between the degradation of sensitivity and the ...

To develop in vivo monitoring meter for pH measurements is still the bottleneck for understanding the role of pH plays in the brain diseases. In this work, a selective and sensitive electrochemical pH ...

Intracellular pH is an important indicator for cellular metabolism and pathogenesis. pH sensing in living cells has been achieved using a number of synthetic organic dyes and genetically expressible ...
