Therefore, dependent on the surface properties, nanomaterials efficiently adsorb biomolecules and form a so-called biomolecular corona. This passive, nontargeted adsorption might be utilized to bind viruses, provided that the selected nanomaterial is relatively biocompatible. Viral surface proteins are often modified by sugar moieties or encompass positively charged amino acid patches that bind to lectins or glycosaminoglycans (GAGs) of heparan sulfate (HS), respectively.32 Robust interactions of virus particles with these host receptors is ensured by multivalent binding, which is likely why single-molecule inhibitors often are not capable of efficiently perturbing this key event but multivalent NPs are superior to block binding of different viruses to the host cell.125","tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T199","span":{"begin":399,"end":407},"obj":"Body_part"},{"id":"T200","span":{"begin":430,"end":435},"obj":"Body_part"},{"id":"T201","span":{"begin":477,"end":487},"obj":"Body_part"},{"id":"T202","span":{"begin":520,"end":538},"obj":"Body_part"},{"id":"T203","span":{"begin":540,"end":544},"obj":"Body_part"},{"id":"T204","span":{"begin":549,"end":564},"obj":"Body_part"},{"id":"T205","span":{"begin":566,"end":568},"obj":"Body_part"},{"id":"T206","span":{"begin":880,"end":884},"obj":"Body_part"}],"attributes":[{"id":"A199","pred":"fma_id","subj":"T199","obj":"http://purl.org/sig/ont/fma/fma67257"},{"id":"A200","pred":"fma_id","subj":"T200","obj":"http://purl.org/sig/ont/fma/fma82737"},{"id":"A201","pred":"fma_id","subj":"T201","obj":"http://purl.org/sig/ont/fma/fma82739"},{"id":"A202","pred":"fma_id","subj":"T202","obj":"http://purl.org/sig/ont/fma/fma63011"},{"id":"A203","pred":"fma_id","subj":"T203","obj":"http://purl.org/sig/ont/fma/fma63011"},{"id":"A204","pred":"fma_id","subj":"T204","obj":"http://purl.org/sig/ont/fma/fma63023"},{"id":"A205","pred":"fma_id","subj":"T205","obj":"http://purl.org/sig/ont/fma/fma63023"},{"id":"A206","pred":"fma_id","subj":"T206","obj":"http://purl.org/sig/ont/fma/fma68646"},{"subj":"T199","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T200","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T201","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T202","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T203","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T204","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T205","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T206","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T399","span":{"begin":38,"end":39},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T400","span":{"begin":70,"end":71},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T401","span":{"begin":211,"end":212},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T402","span":{"begin":307,"end":314},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T403","span":{"begin":610,"end":615},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T404","span":{"begin":860,"end":867},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T405","span":{"begin":880,"end":884},"obj":"http://purl.obolibrary.org/obo/GO_0005623"}],"attributes":[{"subj":"T399","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T400","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T401","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T402","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T403","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T404","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T405","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T337","span":{"begin":236,"end":242},"obj":"Chemical"},{"id":"T338","span":{"begin":399,"end":407},"obj":"Chemical"},{"id":"T339","span":{"begin":477,"end":487},"obj":"Chemical"},{"id":"T340","span":{"begin":477,"end":482},"obj":"Chemical"},{"id":"T341","span":{"begin":483,"end":487},"obj":"Chemical"},{"id":"T342","span":{"begin":520,"end":538},"obj":"Chemical"},{"id":"T343","span":{"begin":540,"end":544},"obj":"Chemical"},{"id":"T344","span":{"begin":549,"end":564},"obj":"Chemical"},{"id":"T345","span":{"begin":549,"end":556},"obj":"Chemical"},{"id":"T346","span":{"begin":557,"end":564},"obj":"Chemical"},{"id":"T347","span":{"begin":566,"end":568},"obj":"Chemical"},{"id":"T349","span":{"begin":714,"end":722},"obj":"Chemical"},{"id":"T350","span":{"begin":723,"end":733},"obj":"Chemical"},{"id":"T351","span":{"begin":813,"end":816},"obj":"Chemical"}],"attributes":[{"id":"A337","pred":"chebi_id","subj":"T337","obj":"http://purl.obolibrary.org/obo/CHEBI_37409"},{"id":"A338","pred":"chebi_id","subj":"T338","obj":"http://purl.obolibrary.org/obo/CHEBI_36080"},{"id":"A339","pred":"chebi_id","subj":"T339","obj":"http://purl.obolibrary.org/obo/CHEBI_33709"},{"id":"A340","pred":"chebi_id","subj":"T340","obj":"http://purl.obolibrary.org/obo/CHEBI_46882"},{"id":"A341","pred":"chebi_id","subj":"T341","obj":"http://purl.obolibrary.org/obo/CHEBI_37527"},{"id":"A342","pred":"chebi_id","subj":"T342","obj":"http://purl.obolibrary.org/obo/CHEBI_18085"},{"id":"A343","pred":"chebi_id","subj":"T343","obj":"http://purl.obolibrary.org/obo/CHEBI_18085"},{"id":"A344","pred":"chebi_id","subj":"T344","obj":"http://purl.obolibrary.org/obo/CHEBI_28815"},{"id":"A345","pred":"chebi_id","subj":"T345","obj":"http://purl.obolibrary.org/obo/CHEBI_24500"},{"id":"A346","pred":"chebi_id","subj":"T346","obj":"http://purl.obolibrary.org/obo/CHEBI_16189"},{"id":"A347","pred":"chebi_id","subj":"T347","obj":"http://purl.obolibrary.org/obo/CHEBI_74056"},{"id":"A348","pred":"chebi_id","subj":"T347","obj":"http://purl.
