Correction to “Glucose‐Sensitive Hydrogel Optical Fibers Functionalized with Phenylboronic Acid“

Concerns were raised by a third party regarding duplicated and rotated image sections within the subpanels of Figure 7c.The authors acknowledged an error in the compilation of the figure.As the comprehensive set of original raw images was no longer available, the authors repeated the experiment using the original protocol described in the manuscript.The new data confirmed that the original experimental results and the overall conclusions of the paper remain unaffected.The corrected Figure 7b,c are provided below.The authors apologize for this oversight.Figure 7. b,c).Biological study of NIH-3T3 fibroblasts for fiber samples: PEGDA, p(AM-co-PEGDA), p(AM-co-PEGDA-co-3-APBA), and no fiber.b,c) LIVE/DEAD assay
