Micelles with ultralow critical micelle concentration as carriers for drug delivery
Open accessAbstract
Conventional micellar carriers disassemble into free surfactants when diluted at concentrations below the critical micelle concentration (CMC). This limits the bioavailability in vivo of injected hydrophobic drugs encapsulated in micellar systems. Here, we show that a micelle comprising a superhydrophilic zwitterionic polymer domain and a superhydrophobic lipid domain has an undetectable CMC below 10−6 mM—a value that is orders of magnitude lower than the CMCs (>10−3 mM) of typical micellar systems. We also show that zwitterionic moieties or zwitterionic polymers added to a micelle solution stabilize the micelles at concentrations below their inherent CMC. In a mouse model of melanoma, ultralow-CMC micelles encapsulating docetaxel led to the complete eradication of tumours, whereas conventional docetaxel micellar formulations did not reverse tumour growth. Ultralow-CMC micelles might become next-generation carriers for drug delivery. Polymer–lipid micelles with an ultralow undetectable critical micelle concentration make ultrastable drug carriers that significantly enhance therapeutic outcomes in a mouse model of melanoma.

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.
