Stimulus-Responsive Polymersomes Loaded with NaErF4@CaF2 Nanoparticles for Precise NIR Lifetime-Based Detection of Microenvironment pH Changes.
External stimulus-responsive nanoplatforms based on biodegradable co-polymers and surfactants were loaded with luminescent nanoparticles for dynamic lifetime-based monitoring of pH changes in solution. In particular, we used PEG-PLGA-based blocks co-stabilized with either amphoteric coco-betaine or nonionic Pluronic F-...
