Correction to “Label‐Free and Regenerative Electrochemical Microfluidic Biosensors for Continual Monitoring of Cell Secretomes”

Concerns were raised by a third party regarding overlapping image panels between the EDX spectra of Figure 2f and Figure S6d (Supporting Information), yet the spots they are reporting on are not the same.The authors explained that the low-magnification SEM image in Figure 2f shows the overall morphology of the electrode, and the red arrow only representatively marked one black spot, the EDX data does not belong to it.The actual spot from which the EDX data was obtained is indicated as Spot 2 in the SEM image of Figure S6c (Supporting Information), with the same EDX data shown again in Figure S6d (Supporting Information).To provide further clarification for the readers, the authors have corrected Figure 2f by removing the red arrow and revising the figure caption.
