There is a constant need for more effective collection method and sensitive chemical analysis, which can detect and resolve the chemical evolution of the nanoparticles in the atmosphere. This study proposed a novel technique that employs the SERS (Surface Enhanced Raman Spectroscopy) substrate as the sampling substrate of a condensational growth tube (CGT) sampler. This new experimental setup ensures simultaneous inertial sampling and SERS pretreatment of individual nanoparticles. Based on the successful detection of the peaks corresponding to sulfate v(SO42-) and organic v(C-H) modes, our proposed method showed sensitivity high enough for detecting major chemical components from individual nanoparticles as small as 20 nm. This can be a significant step forward in our pursuit of developing the more sensitive chemical analysis.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:18H03355, 研究期間(年度):2018-04-01 - 2021-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「超微小エアロゾルの革新的捕集法の開発と応用に基づく新粒子生成時の化学的動態解明」研究成果報告書　課題番号18H03355\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-18H03355/18H03355seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00057804","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学環日本海域環境研究センター"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=90505728"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=90505728","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-18H03355/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-18H03355/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-18H03355/18H03355seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-18H03355/18H03355seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-02-17"}],"displaytype":"detail","filename":"OC-PR-MATSUKI-A-kaken 2021-24p.pdf","filesize":[{"value":"602.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"OC-PR-MATSUKI-A-kaken 2021-24p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/51501/files/OC-PR-MATSUKI-A-kaken 2021-24p.pdf"},"version_id":"00ac9f5f-dc17-4543-a77c-ffd29842be91"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"超微小エアロゾルの革新的捕集法の開発と応用に基づく新粒子生成時の化学的動態解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超微小エアロゾルの革新的捕集法の開発と応用に基づく新粒子生成時の化学的動態解明"},{"subitem_title":"Characterization of chemical dynamics of new particle formation based on the development and application of novel collection method for ultra-fine aerosols","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["4014"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-02-17"},"publish_date":"2022-02-17","publish_status":"0","recid":"51501","relation_version_is_last":true,"title":["超微小エアロゾルの革新的捕集法の開発と応用に基づく新粒子生成時の化学的動態解明"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:50:50.734646+00:00"}
