The use of nanostructured Cu surfaces would further enhance their antimicrobial activity. Moreover, these NPs could inactivate viruses if sprayed on contaminated surfaces or loaded onto textile fabrics to confer antimicrobial properties (masks, blouses, etc.). Indeed, CuO-impregnated masks have shown remarkable anti-influenza virus (H1N1 and H9N2) activity under simulated breathing conditions,172 and the activity of these materials toward SARS-CoV-2 should be investigated. The viral disinfectant properties of Ag NPs and CuO NPs is further enhanced when they are combined with Fe as bimetallic particles, due to coupled redox reactions between the two metals.173","tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T305","span":{"begin":81,"end":86},"obj":"Body_part"},{"id":"T306","span":{"begin":791,"end":793},"obj":"Body_part"}],"attributes":[{"id":"A305","pred":"fma_id","subj":"T305","obj":"http://purl.org/sig/ont/fma/fma68646"},{"id":"A306","pred":"fma_id","subj":"T306","obj":"http://purl.org/sig/ont/fma/fma61898"},{"subj":"T305","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T306","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T183","span":{"begin":594,"end":603},"obj":"Disease"},{"id":"T184","span":{"begin":719,"end":727},"obj":"Disease"}],"attributes":[{"id":"A183","pred":"mondo_id","subj":"T183","obj":"http://purl.obolibrary.org/obo/MONDO_0005812"},{"id":"A184","pred":"mondo_id","subj":"T184","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"subj":"T183","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T184","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T535","span":{"begin":81,"end":86},"obj":"http://purl.obolibrary.org/obo/GO_0005623"},{"id":"T536","span":{"begin":171,"end":172},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T537","span":{"begin":356,"end":364},"obj":"http://purl.obolibrary.org/obo/CLO_0001658"},{"id":"T538","span":{"begin":403,"end":410},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T539","span":{"begin":604,"end":609},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T540","span":{"begin":626,"end":634},"obj":"http://purl.obolibrary.org/obo/CLO_0001658"},{"id":"T541","span":{"begin":684,"end":692},"obj":"http://purl.obolibrary.org/obo/CLO_0001658"}],"attributes":[{"subj":"T535","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T536","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T537","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T538","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T539","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T540","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T541","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T38053","span":{"begin":0,"end":2},"obj":"Chemical"},{"id":"T27506","span":{"begin":47,"end":49},"obj":"Chemical"},{"id":"T10490","span":{"begin":50,"end":54},"obj":"Chemical"},{"id":"T94671","span":{"begin":260,"end":262},"obj":"Chemical"},{"id":"T25241","span":{"begin":263,"end":266},"obj":"Chemical"},{"id":"T85587","span":{"begin":302,"end":304},"obj":"Chemical"},{"id":"T8300","span":{"begin":342,"end":355},"obj":"Chemical"},{"id":"T54891","span":{"begin":488,"end":501},"obj":"Chemical"},{"id":"T56066","span":{"begin":764,"end":776},"obj":"Chemical"},{"id":"T22825","span":{"begin":791,"end":793},"obj":"Chemical"},{"id":"T51397","span":{"begin":858,"end":860},"obj":"Chemical"},{"id":"T77186","span":{"begin":933,"end":939},"obj":"Chemical"}],"attributes":[{"id":"A18496","pred":"chebi_id","subj":"T38053","obj":"http://purl.obolibrary.org/obo/CHEBI_28694"},{"id":"A47129","pred":"chebi_id","subj":"T27506","obj":"http://purl.obolibrary.org/obo/CHEBI_28694"},{"id":"A34023","pred":"chebi_id","subj":"T10490","obj":"http://purl.obolibrary.org/obo/CHEBI_24870"},{"id":"A52132","pred":"chebi_id","subj":"T94671","obj":"http://purl.obolibrary.org/obo/CHEBI_28694"},{"id":"A50060","pred":"chebi_id","subj":"T25241","obj":"http://purl.obolibrary.org/obo/CHEBI_24870"},{"id":"A87497","pred":"chebi_id","subj":"T85587","obj":"http://purl.obolibrary.org/obo/CHEBI_28694"},{"id":"A68313","pred":"chebi_id","subj":"T8300","obj":"http://purl.obolibrary.org/obo/CHEBI_33281"},{"id":"A1991","pred":"chebi_id","subj":"T54891","obj":"http://purl.obolibrary.org/obo/CHEBI_33281"},{"id":"A42597","pred":"chebi_id","subj":"T56066","obj":"http://purl.obolibrary.org/obo/CHEBI_48219"},{"id":"A75325","pred":"chebi_id","subj":"T22825","obj":"http://purl.obolibrary.org/obo/CHEBI_30512"},{"id":"A89262","pred":"chebi_id","subj":"T22825","obj":"http://purl.obolibrary.org/obo/CHEBI_9141"},{"id":"A84569","pred":"chebi_id","subj":"T51397","obj":"http://purl.obolibrary.org/obo/CHEBI_18248"},{"id":"A18375","pred":"chebi_id","subj":"T77186","obj":"http://purl.obolibrary.org/obo/CHEBI_33521"},{"subj":"T38053","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T27506","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T10490","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T94671","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T25241","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T85587","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T8300","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T54891","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T56066","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T22825","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T51397","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T77186","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"
