The pH-responsive PEGylated nanogels composed of the cross-linked poly[2-(N,N-diethylamino)ethyl methacrylatej-copoly(2,2,2-trifluoroethyl methacrylate) gel core showed a remarkable on-off regulation of 19F magnetic resonance signal intensity (T 2 values) as well as signal-to-noise ratios in response to extracellular pH 6.5 of tumor environment under 19F magnetic resonance spectroscopic imaging (MRS/I), demonstrating the utility of the PEGylated nanogels as solid tumor-specific 19F MPJ/S nanoprobes.
