To extend optical trapping towards the nano-regime, in this work we demonstrate trapping of single nanoparticles in arrays of plasmonic coaxial nano-apertures with various inner disk sizes and theoretically estimate the associated forces. A high normalized experimental trap stiffness of 3.50 fN nm⁻¹ mW⁻¹ μm⁻² for 20 nm polystyrene particles is observed for an optimum design of 149 nm for the nanodisk diameter at a trapping wavelength of 980 nm. Theoretical simulations are used to interpret the enhancement of the observed trap stiffness. A quick particle trapping time of less than 8 s is obtained at a concentration of 14 x 10¹¹ particles ml⁻¹ with low incident laser intensity of 0.59 mW μm⁻². This good trapping performance with fast delivery of nanoparticles to multiple trapping sites emerges from a combination of the enhanced electromagnetic near-field and spatial temperature increase. This work has applications in nanoparticle delivery and trapping with high accuracy, and bridges the gap between optical manipulation and nanofluidics.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing Ltd."}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/32992307","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1088/1361-6528/abbca9","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1361-6528/abbca9","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 The Author(s)."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0957-4484","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1361-6528","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-09"}],"displaytype":"detail","filename":"Bouloumis_2021_Nanotechnology_32_025507.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International(https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Bouloumis_2021_Nanotechnology_32_025507","url":"https://oist.repo.nii.ac.jp/record/1833/files/Bouloumis_2021_Nanotechnology_32_025507.pdf"},"version_id":"c9ff29f5-d86d-4ae4-b392-978bcbd283d7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"nanoparticles","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nanostructured array","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optical forces","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plasmonic optical tweezers","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"coaxial aperture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"trap stiffness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"trapping time","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Fast and efficient nanoparticle trapping using plasmonic connected nanoring apertures","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fast and efficient nanoparticle trapping using plasmonic connected nanoring apertures","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"30","path":["47"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-12-09"},"publish_date":"2020-12-09","publish_status":"0","recid":"1833","relation_version_is_last":true,"title":["Fast and efficient nanoparticle trapping using plasmonic connected nanoring apertures"],"weko_creator_id":"30","weko_shared_id":30},"updated":"2023-06-26T11:41:50.105324+00:00"}
