The authors regret <In the original manuscript, the Fig. 2 CD44 2W in PFP@NDs-PEG-SDF-1α (i.v.)+PFP@NDs-PEG-SDF-1α/hydrogel+US Group is arranged the mistaken image during the assembly of Fig. 2. The Fig. S3A PFP@NDs-PEG 48 h Group is arranged the mistaken images during the assembly of Fig. S3. The Fig. S4B PFP@NDs-PEG-SDF-1α/Hydrogel Group is arranged the mistaken image during the assembly of Fig. S4. The corresponding images have been corrected. This correction does not alter the findings or conclusion of this work. The author sincerely apologizes for the oversight of this part. The corrected Fig. 2, Figs. S3 and S4 are presented below>.
