Corrigendum to “Multifunctional hydrogel sensor with Tough, self-healing capabilities and highly sensitive for motion monitoring and wound healing” [Chem. Eng. J. 497 (2024) 154890]

Abstract

The authors regret they found an error in Fig. 5e and Fig. 6g. The green channel in Fig. 5e, f should be labeled as CD68 instead of CD86, and we mistakenly used the MHPBA-GO group images in Figs. 5e and 6e. This error was caused by confusion in folder naming during image classification. We have attached the correct MHPBA-GO group images in Figs. 5e and 6g. The fluorescence images in Figs. 5e and 6g are intended to semi-quantitatively highlight the differences in INOS and CD31 positivity between different groups. The INOS and CD31 positivity of the MHPBA-GO group in Figs. 5e and 6g was originally calculated based on the images of the MHPBA-GO group, and the results remain unchanged. This correction does not affect the conclusions of this paper. We sincerely apologize for the inconvenience caused and hope to correct this error by providing the corrected Figs. 5e and 6g.

(b) Live/Dead staining of L929 cells after being treated with MHPBA-GO hydrogels for 1, 2, and 3 days, respectively, scale bar: 100 µm. (c) Images of survival bacteria (E. coli and S. aureus) clones on culture plates after contact with the control, HPBA, MHPBA-GO, and MHPBA-GO Laser groups respectively (n = 3). (d) Bacterial viability in control, HPBA, MHPBA-GO, and MHPBA-GO Laser groups (n = 3) against E. coli and S. aureus. (e) Fluorescence images and (g) quantitative analysis of INOS after treatment with DHE (n = 3). (f) Fluorescence images and (h) quantitative analysis of CD206 after treatment with DHE (n = 3). (i) Quantitative analysis of the M2/M1 ratio. The scale bar in e and f is 50 μm. INOS (red): M1 macrophages, CD206 (red): M2 macrophages and nuclei were stained with DAPI (blue), data are shown as mean ± SD (n = 3). *p < 0.05, **p < 0.01, ***p < 0.001.
