(A). Polyelectrolyte solution with a specified charge in a dipping container. The substrate is immersed in this solution for a predetermined time. (B). The coated substrate is placed in water to wash off the excess, unbound polyelectrolyte solution. (C). The washed, coated substrate is immersed in a polyelectrolyte solution of an opposite charge relative to the first solution. (D). A bilayer of the polycation and -anion is formed. The excess of the second polyelectrolyte (blue) is washed off to produce a substrate with a single bilayer of the polyelectrolytes as a nanocoating. The process is repeated for the desired amount of cycles.","tracks":[{"project":"LitCovid-PD-CLO","denotations":[{"id":"T473","span":{"begin":0,"end":1},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T474","span":{"begin":58,"end":59},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T475","span":{"begin":92,"end":93},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T476","span":{"begin":114,"end":115},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T477","span":{"begin":182,"end":183},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T478","span":{"begin":205,"end":206},"obj":"http://purl.obolibrary.org/obo/CLO_0001021"},{"id":"T479","span":{"begin":356,"end":357},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T480","span":{"begin":437,"end":443},"obj":"http://www.ebi.ac.uk/efo/EFO_0000265"},{"id":"T481","span":{"begin":565,"end":566},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T482","span":{"begin":582,"end":583},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T483","span":{"begin":626,"end":627},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T473","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T474","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T475","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T476","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T477","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T478","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T479","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T480","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T481","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T482","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T483","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T572","span":{"begin":78,"end":86},"obj":"Chemical"},{"id":"T573","span":{"begin":169,"end":177},"obj":"Chemical"},{"id":"T574","span":{"begin":243,"end":248},"obj":"Chemical"},{"id":"T575","span":{"begin":281,"end":296},"obj":"Chemical"},{"id":"T577","span":{"begin":297,"end":305},"obj":"Chemical"},{"id":"T578","span":{"begin":358,"end":373},"obj":"Chemical"},{"id":"T580","span":{"begin":374,"end":382},"obj":"Chemical"},{"id":"T581","span":{"begin":427,"end":435},"obj":"Chemical"},{"id":"T582","span":{"begin":459,"end":469},"obj":"Chemical"},{"id":"T584","span":{"begin":475,"end":480},"obj":"Chemical"},{"id":"T585","span":{"begin":517,"end":532},"obj":"Chemical"},{"id":"T587","span":{"begin":606,"end":622},"obj":"Chemical"}],"attributes":[{"id":"A572","pred":"chebi_id","subj":"T572","obj":"http://purl.obolibrary.org/obo/CHEBI_75958"},{"id":"A573","pred":"chebi_id","subj":"T573","obj":"http://purl.obolibrary.org/obo/CHEBI_75958"},{"id":"A574","pred":"chebi_id","subj":"T574","obj":"http://purl.obolibrary.org/obo/CHEBI_15377"},{"id":"A575","pred":"chebi_id","subj":"T575","obj":"http://purl.obolibrary.org/obo/CHEBI_53369"},{"id":"A576","pred":"chebi_id","subj":"T575","obj":"http://purl.obolibrary.org/obo/CHEBI_61446"},{"id":"A577","pred":"chebi_id","subj":"T577","obj":"http://purl.obolibrary.org/obo/CHEBI_75958"},{"id":"A578","pred":"chebi_id","subj":"T578","obj":"http://purl.obolibrary.org/obo/CHEBI_53369"},{"id":"A579","pred":"chebi_id","subj":"T578","obj":"http://purl.obolibrary.org/obo/CHEBI_61446"},{"id":"A580","pred":"chebi_id","subj":"T580","obj":"http://purl.obolibrary.org/obo/CHEBI_75958"},{"id":"A581","pred":"chebi_id","subj":"T581","obj":"http://purl.obolibrary.org/obo/CHEBI_75958"},{"id":"A582","pred":"chebi_id","subj":"T582","obj":"http://purl.obolibrary.org/obo/CHEBI_60684"},{"id":"A583","pred":"chebi_id","subj":"T582","obj":"http://purl.obolibrary.org/obo/CHEBI_53323"},{"id":"A584","pred":"chebi_id","subj":"T584","obj":"http://purl.obolibrary.org/obo/CHEBI_22563"},{"id":"A585","pred":"chebi_id","subj":"T585","obj":"http://purl.obolibrary.org/obo/CHEBI_53369"},{"id":"A586","pred":"chebi_id","subj":"T585","obj":"http://purl.obolibrary.org/obo/CHEBI_61446"},{"id":"A587","pred":"chebi_id","subj":"T587","obj":"http://purl.obolibrary.org/obo/CHEBI_53369"},{"id":"A588","pred":"chebi_id","subj":"T587","obj":"http://purl.obolibrary.org/obo/CHEBI_61446"},{"subj":"T572","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T573","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T574","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T575","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T577","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T578","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T580","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T581","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T582","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T584","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T585","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T587","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"1447","span":{"begin":243,"end":248},"obj":"Chemical"}],"at
