A new nanogel indicator (NGI) for ratiometric fluorescent detection of intracellular pH values has been reported. In aqueous solution, the NGI can be used for ratiometric sensing of pH changes with a large hypsochromic shift of 100 nm in the green–red region and reversible. Furthermore, the NGI has been used to calibrate the cytosol pH in living cells.
