We have shown the CND to be a novel photoluminescent probe for nitrite based on the specific reaction via aryl radicals generated from p-phenylenediamine diazotized by the nitrite. In the present method, nitrite can be selectively detected down to 1 uM over several anions, such as nitrate, perchlorate, sulfate, fluoride, chloride, and bromide at mM levels. The photoactivity is also investigated by comparing six CNDs prepared from organic precursors having different elemental compositions. As a consequence, hetero atoms such as nitrogen and sulfur had a striking effect on the quantum yield. CND prepared from glutathione showed the quantum yield of 0.46. These results present evidence of the value of chemical modification of CNDs including the chemical reactivity of CND itself and hetero-atom doping.","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:25810083, 研究期間(年度):2013-04-01 - 2015-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「化学修飾カーボンナノドットによる生体関連物質・イオンの蛍光センシング」課題番号25810083\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-25810083/25810083seika/）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":"10.24517/00056749","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理工研究域物質化学系"}]},"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=70396430"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=70396430","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25810083/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25810083/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-25810083/25810083seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-25810083/25810083seika/","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森田, 耕太郎"}],"nameIdentifiers":[{"nameIdentifier":"2251","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70396430","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70396430"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-03"}],"displaytype":"detail","filename":"SC-PR-MORITA-K-kaken 2015-4p.pdf","filesize":[{"value":"343.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-MORITA-K-kaken 2015-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/50440/files/SC-PR-MORITA-K-kaken 2015-4p.pdf"},"version_id":"38b79b00-3ce4-4d00-a3de-d244512358d5"}]},"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":"化学修飾カーボンナノドットによる生体関連物質・イオンの蛍光センシング","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"化学修飾カーボンナノドットによる生体関連物質・イオンの蛍光センシング"},{"subitem_title":"Photoluminescent detection of biological materials and ions by chemically modified carbon nano dots","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2819"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-02-03"},"publish_date":"2020-02-03","publish_status":"0","recid":"50440","relation_version_is_last":true,"title":["化学修飾カーボンナノドットによる生体関連物質・イオンの蛍光センシング"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T05:46:03.896369+00:00"}
