There are similarities between some FT-IR spectra reported in Fig 2 of this article [1] and those published in other articles by some of the same authors. Specifically:

  • The PVA spectrum in Fig 2A of [1] appears similar to the PVA spectrum in Fig 5 of [2];
  • The SF spectrum in Fig 2A [1] appears similar to the SF spectrum in Fig 4 of [3] and the silk fibroin spectrum in Fig 5 of [4];
  • The FNP spectrum in Fig 2D of [1] appears similar to the FNP spectrum in Fig 5C of [4].

With this notice, the authors clarify that the similar FT‑IR spectra reflect the use of the same compounds, which served as controls or base materials in the experiments.

In addition, contrary to the Data Availability statement in [1], the individual-level underlying data supporting the article’s results were not provided. The quantitative data underlying Figs 1, 3, 5, and Tables 1-3 are provided with this notice as S1-S6 Files.
