In the original article [1], there was a mistake in the position of one of the OH of N-acetylgalactosamine. In the original article [1], the OH was in an equatorial position and it should be in an axial position. This mistake affected Scheme 1 and Scheme 2. Below, we include the figures from the original manuscript and the figures that are corrected. We apologize for this unintentional mistake.
Original Scheme 1:
Scheme 1.
Chemical schemes of potential multifunctional GalNAc derivatives including (A) tetrameric G-quadruplexes studied in this work and (B) the triantennary GalNAc.
Scheme 1.
Chemical schemes of potential multifunctional GalNAc derivatives including (A) tetrameric G-quadruplexes studied in this work and (B) the triantennary GalNAc.

This should be replaced with the following:
Scheme 1.

Original Scheme 2:
Scheme 2.
Chemical structures of the GalNAc and FAM ligands used in this work.
Scheme 2.
Chemical structures of the GalNAc and FAM ligands used in this work.

This should be replaced with the following:
Scheme 2.
Chemical structures of the GalNAc and FAM ligands used in this work.
