Correction to “Flexible 3D Plasmonic Web Enables Remote Surface Enhanced Raman Spectroscopy”

Adv. Sci. 2024, 11, 2402192.

We committed a series of errors that led us to assume that glyphosate (GLY, CAS 287399-31-9), one of the model analytes, was analyzed at the yM level as follows: First, we had an error related to units’ conversion, hence mathematically (but not experimentally) our analysis was virtually carried out in a volume of 100 L (instead of 1 mL, which was the experimental volume). Consequently, we wrongly assumed that those spectra related to GLY concentrated at yM level and lower concentration levels were feasible to record. However, as discussed above, the analysis of GLY at yM level (and lower concentration levels) is only achievable in the analysis of a volume of 100 L. Hence, we recognize that those spectra originally attributed to GLY concentrated at yM level and lower concentration levels correspond to contaminated samples. Consequently, a series of corrections are detailed below. We also recognize that given the ultrasensitive character of the reported innovative surface-enhanced Raman spectroscopy (SERS) substrate, the substrate can be easily contaminated.

This series of errors does not affect our findings and conclusions since the ultrasensitive character and the operating mechanism of our innovative SERS substrate is supported by the overall content of the manuscript. The authors regret this scenario and apologize for any inconvenience caused.

Figures

Figure 2 (panel c,d) needs a correction which is reflected in the updated figure below. Particularly, in Figure 2c, the curves related to yM and 10⁻²⁷ M were removed in the corrected Figure 2. In addition, the corrected Figure 2d displays the SERS spectra corresponding to the analysis of GLY concentrated at 10⁻²¹ M.
