Correction to Amphiphilic Polysaccharide Block Copolymers for pH-Responsive Micellar Nanoparticles Benjamin B. Breitenbach, Ira Schmid, and Peter R. Wich* Biomacromolecules 2017, 18 (9), 2839−2848. DOI: 10.1021/acs.biomac.7b00771 chemistry. The correct block copolymer should contain units in both blocks. We apologize for this error and hereby provide the revised images with the correct stereochemistry.

We found an error in the graphical abstract, Scheme 1, and Figure 2 of our recently published article. In each image of the block copolymer (4), the glucose units on the right side were mirrored and therefore drawn with the wrong stereo-

Figure 2. 1H NMR spectra of Dex-b-AcDex block copolymer 4 in D2O (a) and D2O + DCl (b) (300 MHz). Spectrum (a) shows the characteristic signal of the acetal protons (H-g, H-h) as well as signals of both aromatic linker H-a-e′ and the formed triazole proton H-c. Adding a few drops of DCl cleaves the acetals and forms methanol and acetone (H-i and H-j in spectrum (b)).
