{"doi":"10.1016/j.jhin.2022.12.023","title":"Antimicrobial efficacy and inactivation kinetics of a novel LED-based UV-irradiation technology","abstract":"BACKGROUND: Ultraviolet (UV)-light-emitting diodes (UV-LEDs) are energy efficient and of special interest for the inactivation of micro-organisms. In the context of the coronavirus disease 2019 pandemic, novel UV technologies can offer a powerful alternative for effective infection prevention and control. METHODS: This study assessed the antimicrobial efficacy of UV-C LEDs on Escherichia coli, Pseudomonas fluorescens and Listeria innocua, as well as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), human immunodeficiency virus-1 (HIV-1) and murine norovirus (MNV), dried on inanimate surfaces, based on European Standard EN 17272. RESULTS: ) for inactivation. Regarding inactivation, non-enveloped MNV required much higher UV doses for all tested wavelengths compared with SARS-CoV-2 or HIV-1. CONCLUSION: Overall, the results support the use of LEDs emitting at shorter wavelengths of the UV-C spectrum to inactivate bacteria as well as enveloped and non-enveloped viruses by exposure to the appropriate UV dose. However, low availability and excessive production costs of shortwave UV-C LEDs restricts implementation at present, and supports the use of longwave UV-C LEDs in combination with higher irradiation doses.","journal":"Journal of Hospital Infection","year":2023,"id":332580,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":24,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9619,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":667887,"name":"Gabriel Diem","orcid":"0000-0002-8737-005X","position":1,"is_corresponding":false},{"id":1059814,"name":"J Kiechl","orcid":null,"position":2,"is_corresponding":false},{"id":1059815,"name":"Daniela Chisté","orcid":null,"position":3,"is_corresponding":false},{"id":1059213,"name":"Giulia Bertacchi","orcid":"0000-0001-7346-7603","position":4,"is_corresponding":false},{"id":1059214,"name":"Astrid Mayr","orcid":"0000-0002-8742-2817","position":5,"is_corresponding":false},{"id":667893,"name":"Doris Wilflingseder","orcid":"0000-0002-5888-5118","position":6,"is_corresponding":false},{"id":235822,"name":"Cornelia Lass‐Flörl","orcid":"0000-0002-2946-7785","position":7,"is_corresponding":false},{"id":1059816,"name":"W Posch","orcid":null,"position":8,"is_corresponding":false},{"id":741820,"name":"Harald Schöbel","orcid":"0000-0001-7540-0867","position":0,"is_corresponding":true}],"reference_count":41,"raw_metadata":null,"created_at":"2026-07-19T01:09:35.125543Z","pmid":"36754288","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
