Imaging all the people: Using ionizable diblock copolymers a series of nanoprobes encoded with different 19F reporters for specific pH transitions is prepared for use in MRI. The pH response of the nanoprobes is extremely sharp (ΔpHON/OFF≈0.25 pH), and results from the disassembly of polymer micelles (see scheme). A collection of three nanoprobes provides the proof of concept and allows for a qualitative measurement of environmental pH values.
