Formation of colloidal gold nanoparticles was monitored by absorption spectroscopy, light scattering, and zeta potential measurements. Colloidal gold nanoparticles were obtained when the ratio of AuCl_4^- and AET was about 1:1.5. The mean size and the zeta potential of the nanoparticles was 34±6 nm and +44±24 mV, respectively. The polyethyleneoxide compound terminated with a SH group (PEG-SH) increased the mean size of the nanoparticles (49±18 nm), but decreased zeta potentials of the gold nanoparticles (+16±7 mV). The PEG-SH was effective to stabilize the colloidal dispersion of the gold nanoparticles.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"分析化学, 54(6), pp. 521-526; 2005","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71454","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawano, Takahito"}]},{"nameIdentifiers":[{"nameIdentifier":"71455","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Horiguchi, Yukichi"}]},{"nameIdentifiers":[{"nameIdentifier":"71456","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Niidome, Yasuro"}]},{"nameIdentifiers":[{"nameIdentifier":"71457","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Niidome, Takuro"}]},{"nameIdentifiers":[{"nameIdentifier":"71458","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamada, Sunao"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.54.521","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The Japan Society for Analytical Chemistry (c) 2005"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河野, 喬仁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"堀口, 諭吉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"新留, 康郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"新留, 琢郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 淳"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"BunsekiKagaku54_521.pdf","filesize":[{"value":"997.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BunsekiKagaku54_521.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/18003/files/BunsekiKagaku54_521.pdf"},"version_id":"fa1f4e64-9164-4765-a813-b1299c50f30e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gold nanoparticles","subitem_subject_scheme":"Other"},{"subitem_subject":"aminoethanethiol","subitem_subject_scheme":"Other"},{"subitem_subject":"zeta potential","subitem_subject_scheme":"Other"},{"subitem_subject":"cationic nanoparticles","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2-アミノエタンチオール塩酸塩を用いるカチオン性金ナノ粒子の調製法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2-アミノエタンチオール塩酸塩を用いるカチオン性金ナノ粒子の調製法"}]},"item_type_id":"2","owner":"2","path":["315"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-05-18"},"publish_date":"2009-05-18","publish_status":"0","recid":"18003","relation_version_is_last":true,"title":["2-アミノエタンチオール塩酸塩を用いるカチオン性金ナノ粒子の調製法"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:13:51.694120+00:00"}
