Add New References

In the original publication [1], there was a mistake in the legend for Figure 1C. Two new references should be added. The legend should contain a foot note as follows: “rGO-PEG was adapted from [12,13]”. The later references are changed accordingly. The correct legend and new references appear below.

Figure 1. Characterization of graphene oxide (GO), reduced graphene oxide (rGO), and PEGylated rGO (rGO-PEG): (A) UV/Vis absorption spectra of graphene derivatives. The optical absorption was measured in 1 cm quartz cuvette on UV/Vis spectrophotometer, and the wavelength range of 200–1000 nm was used. (B) FTIR absorption spectra of graphene derivatives. The optical absorbance was measured on a Nicolet 8700 FTIR instrument (resolution 4 cm⁻¹). The signal recorded from a pure KBr pellet was used as background noise. (C) Representative transmission electron microscope (TEM) images of graphene derivatives. rGO-PEG was adapted from [12,13]. Scale bar, 100 nm. (D) Physicochemical characterization of graphene derivatives. (E) Representative photographs of graphene derivatives diluted in PBS or DMEM as depicted. (F) Determination of bacterial growth on Luria broth (LB) agar plates covered with 50 µg/mL of graphene derivatives. Positive control: Escherichia coli (strain DH5α), red arrow. Scale bar, 2 cm. (G) Quantitative measurement of bacterial endotoxin levels in graphene derivatives. UV/Vis, Ultraviolet-Visible; FTIR, Fourier-transform infrared spectroscopy; GO, graphene oxide; rGO, reduced graphene oxide; rGO-PEG, PEGylated reduced graphene oxide; LB, Luria broth; E. coli, Escherichia coli; EU, endotoxin units.
