Redox-stimuli responsive micelles from DOX-encapsulating polycaprolactone-g-chitosan oligosaccharide

- Chitosan oligosaccharides were clicked onto polycaprolactone backbones (PCL-g-COs).
- Amphiphilic PCL-g-COs self-assembled in solution into core-shell micelles.
- Core cross-clicked nanoparticles with -S-S- linker gave reduction sensitivity.
- Glutathione-mediated DOX release of bioreducible PCL-g-COs micelles.
