    Abstract
    Due to the pandemic, research concerning SARS-CoV-2 became of the utmost importance. In this research, we aimed to find and synthesize a library of peptide epitopes that carry functional properties of the ACE-2 receptor binding to the virus protein for the purpose of creating a therapeutic treatment (i.e. viral inhibition). In order to do this, we used MST to determine binding affinity. After that, we validated the binding properties of our peptide epitopes and applied them as SARSCoV-2 antibody indicators using ELISA. We, then, functionalized gold nanoparticles with the peptide epitopes to assess its utility as a potential SARS-CoV-2 competitive inhibitor. From the set of peptides in the library, P25 showed the most functional properties in both MST and serological ELISA, while P1 successfully conjugated to the gold nanoparticles in different forms (PEG-P1, linker-P1, and mutated P1). Finally, P1 was validated to have antibody binding through sandwich ELISA. In the future, these findings can be applied to inhibit viral activity through drug delivery.

    Export search results

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
