In this study, we investigate the influence of oxygen plasma treatment on structural and localized surface plasmon resonance (LSPR) spectral changes of anisotropic gold nanorods (AuNRs) immobilized on an indium tin oxide (ITO) glass substrate. Unlike AuNRs deposited on a glass slide, no noticeable structural change or deformation of AuNRs on ITO was observed while increasing the oxygen plasma treatment time. This result indicates that ITO provides structural stability to AuNRs immobilized on its surface. Additionally, single-particle scattering spectra of AuNRs showed the broadening of LSPR linewidth within 60\u00a0s of oxygen plasma treatment as a result of the plasmon energy loss contributed from plasmon damping to ITO due to the removal of capping material from the AuNR surface. Nevertheless, an increase in the surface charge on the AuNR surface was observed by narrowing the LSPR linewidth after 180\u00a0s of plasma treatment. The electrochemical study of AuNRs immobilized on ITO electrodes revealed the surface activation and functionalization of AuNRs by increasing plasma treatment. Hence, in this study, a significant understanding of oxygen plasma treatment on AuNRs immobilized on ITO surfaces is provided.<\/jats:p>","DOI":"10.1063\/5.0097220","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T19:04:58Z","timestamp":1655147098000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["Influence of oxygen plasma treatment on structural and spectral changes in gold nanorods immobilized on indium tin oxide surfaces"],"prefix":"10.1063","volume":"157","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4402-8649","authenticated-orcid":false,"given":"Mukunthan","family":"Ramasamy","sequence":"first","affiliation":[{"name":"Energy Harvest-Storage Research Center (EHSRC), University of Ulsan 1 , 93 Daehak-ro, Nam-gu, Ulsan 44610, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0566-8176","authenticated-orcid":false,"given":"Ji Won","family":"Ha","sequence":"additional","affiliation":[{"name":"Energy Harvest-Storage Research Center (EHSRC), University of Ulsan 1 , 93 Daehak-ro, Nam-gu, Ulsan 44610, Republic of Korea"},{"name":"Department of Chemistry, University of Ulsan 2 , 93 Daehak-ro, Nam-gu, Ulsan 44610, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"2023081006060817200_c1","doi-asserted-by":"publisher","first-page":"267","DOI":"10.1146\/annurev.physchem.58.032806.104607","article-title":"Localized surface plasmon resonance spectroscopy and sensing","volume":"58","year":"2007","journal-title":"Annu.
