In the original publication [1], there was an error concerning the interpretation of rubidium (Rb) peak and technetium (Tc) signals. The authors wish to update the text and add definitions of the abbreviations at their first occurrence in Section 3, paragraph 3 as follows:

“The Energy Dispersive Spectroscopy (EDS) analysis of graphene oxide (GO) showed that the analyzed material was predominantly composed of carbon and oxygen. The EDS software also generated small automatic indications assigned to rubidium (Rb) and technetium (Tc). However, these assignments were not independently confirmed. Both indications occurred in spectrally crowded regions susceptible to peak overlap, background effects, low-count statistical noise, and automatic misidentification. The non-conductive sample was coated with gold before SEM/EDS analysis, and the Au M-lines provide a known spectral contribution in the same low-energy region. In addition, technetium is not chemically expected in commercial GO, PLA, pseudoboehmite, or the reagents and preparation materials used in this study, and no plausible technetium source existed in the experimental process. The corresponding software-generated ‘Tc L’ map was weak, speckled, and showed no coherent spatial correlation with the sample morphology. Accordingly, neither the Rb nor the Tc indication should be interpreted as evidence that these elements were genuine constituents of the sample. They are therefore treated as unconfirmed automatic software assignments/artifacts, and the material is interpreted as being predominantly composed of carbon and oxygen, as presented in Figure 3.”
