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 ...

Multi-channel pH sensor based on the color change from the organic dye was examined. Six pH indicators were selected for wide pH measurement range. Absorption spectra of the visible light were ...

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 ...
