Polymer microcapsules as mobile local pH-sensors
Abstract
Polyelectrolyte microcapsules have been loaded with a pH-sensitive, high molecular weight SNARF-1-dextran conjugate. SNARF-1 exhibits a significant pH-dependent emission shift from green to red fluorescence under acidic and basic conditions, respectively. The unique spectral properties of the dye were maintained after the encapsulation. By investigating both human breast cancer cells and fibroblasts, we were able to follow the pH change of the local environment of SNARF-1-filled capsules during the transition from the alkaline cell medium to the acidic endosomal/lysosomal compartments. The incorporation of magnetite nanoparticles and an additional pH-insensitive fluorophore within the capsule shell resulted in a novel type of sensor system based on multifunctional polymer capsules.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
