In the original article, there was a spelling mistake in the name of the second author. The correct name appears above.
In the original article, there were errors in Table 1, page 7, as published. Three reference links and their corresponding references were missing; “Eu3−” should have been “Eu3+”; “0.248 p.m.” should have been “0.248 μM”; “0.13 p1\4” should have been “0.31 μM”; “0.9 [tM” should have been “0.9 μM”; “20 n9.120 pL” should have been “20 ng/20 μL”; the reference Baiv et al. (2018) should have been Baig and Chen (2018) and Cheng et al. (2009) should have been Cheng et al. (2019). There was also a typo in the caption. The corrected Table 1 and its caption, as well as the additional references, appear below.
TABLE 1
| Method | Sensing platform | Detection limit | Ref |
|---|---|---|---|
| Fluorescent | Lanthanide-based surface receptor | 25 nM | Yilmaz et al. (2010) |
| Fluorescent | Hetero MOF | 0.248 μM | Shen et al. (2020) |
| Fluorescent/colorimetric | Eu3+-modified AuNPs | 0.31 μM for colorimetric and 17 nM for fluorescent assay | Yin and Tong (2021) |
| Colorimetric | Gold nanoparticles | 2 μM | Baig and Chen (2018) |
| Colorimetric | Upconversion nanoparticles | 0.9 μM | Cheng et al. (2019) |
| SERS | AgNPs | 20 ng/20 μL | Bell et al. (2005) |
| SERS | AgNPs | 29.9 nM | Cowcher et al. (2013) |
| SERS | AgNPs | 15 nM | This work |
Comparison of different methods for DPA detection.
In the original article, the abbreviation of DMs-PDMS was wrongly modified during production. Corrections have been made to the abstract, page 1. The third sentence previously stated:
“The as prepared DMs embedded PDMS DMs PD MS film was integrated with a microfluidic technique to enhance the SERS signal of a liquid substrate.”
The corrected sentence is as follows:
“The as prepared DMs embedded PDMS (DMs-PDMS) film was integrated with a microfluidic technique to enhance the SERS signal of a liquid substrate.”
Additionally, all instances of the abbreviation “DMs PDMS” have been corrected to “DMs-PDMS” throughout the abstract, page 1; Introduction, page 2, last paragraph; Material and methods sub-heading, “Fabrication of the DMs PDMS film”, page 2; as well as the Results and discussion subheading, “DERS effect investigation of the DMs PDMS film”, page 3.
In the original article, there was an error in Figure 3 as published. For the repeatability study, the SERS spectra and the relative standard deviation value were obtained from 20 random spots, as shown in Figure 3C, not 15. The corrected Figure 3 and its caption appear below.
FIGURE 3
Consequently, in Results and discussion, “Sensing performance evaluation”, page 4, “15 randomly selected spots” should be “20 randomly selected spots”.
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
