Abstract
Correction for ‘Acetalated dextran based nano- and microparticles: synthesis, fabrication, and therapeutic applications’ by Shiqi Wang et al., Chem. Commun., 2021, DOI: 10.1039/d1cc00811k.
The authors regret that there was an error in the chemical structures presented in Fig. 1c and e. The correct Fig. 1 is given below.

| Fig. 1 Schematic synthesis reactions of Ac-DEX and its representative derivatives. (a) Ac-DEX, synthesized from dextran and 2-methoxypropene, catalysed by PPTS.8 (b) Other acetal modified dextran. Ace-DEX, synthesized from dextran and 2-ethoxypropene.12 Spiralcyclic Ac-DEX, synthesized from dextran and cyclic enol ethers (1-methoxycyclopentene, 1-methoxycyclohexene, or 1-methoxycycloheptene).18 (c) Amine-modified dextran synthesis, by partially oxidation of dextran, acetalation, imine bond formation and reduction.19,20,23 (d) Grafted Ac-DEX polymers by conjugation of a chain transfer agent (CTA), followed by reversible addition–fragmentation chain-transfer (RAFT) polymerization.26,28,29 (e) Amphiphilic Ac-DEX block copolymers, synthesized by Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC) click reaction.31,32 | ||
