    Antibodies
    SentencesResources
    Further infection evaluation was done by labeling of SARS-CoV-2 particles with an anti-spike antibody and performing lactate dehydrogenase (LDH) assay, all described below.
    anti-spike
    suggested: None
    LDH
    suggested: None
    SARS-CoV-2 viral particles were labelled with monoclonal rabbit anti-Spike S1 subunit antibodies (Novusbio, clone CR3022), the plate was incubated for 3 hours at room temperature, and after washes with PBST, incubated with secondary anti-rabbit IgG – FITC labelled antibodies (Ref: 65-6111/ lot: UG285467, Invitrogen).
    anti-Spike S1 subunit antibodies ( Novusbio ,
    suggested: None
    anti-rabbit IgG
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Biocompatibility of functionalized materials: To assess if the cotton or PU materials functionalized with GNP or GO were toxic to cells in the absence of virus, A549 lung cancer cells (ATCC) were incubated with material-exposed medium.
    A549
    suggested: NCI-DTP Cat# A549, RRID:CVCL_0023)
    Software and Algorithms
    SentencesResources
    Prior to perform the “Measure” tool of ImageJ, images were processed with the "Smooth" and "Convert to Mask".
    ImageJ
    suggested: (ImageJ, RRID:SCR_003070)
    Microsoft Excel (2010) and Prism6 software (GraphPad) were used to compile and analyze data.
    Microsoft Excel
    suggested: (Microsoft Excel, RRID:SCR_016137)
    GraphPad
    suggested: (GraphPad Prism, RRID:SCR_002798)

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.

    Results from TrialIdentifier: No clinical trial numbers were referenced.


    Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).


    Results from JetFighter: We did not find any issues relating to colormaps.


    Results from rtransparent:

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
