In this study, the AuPt@BaTiO3 bimetallic alloy Schottky junction is prepared to act as oxidase mimetics, and its photo\u2212piezoelectric effect is investigated. The synergy between the photo\u2212piezoelectric effect and the local surface plasmon resonance enhances the directional migration and separation of photogenerated electrons, as well as hot electrons induced by the AuPt bimetallic alloy. This synergy significantly improves the oxidase\u2212like activity. A GSH colorimetric detection platform is developed based on this fading principle. Leveraging the photo\u2212piezoelectric effect allows for highly sensitive detection with a low detection limit (0.225 \u03bcM) and reduces the detection time from 10 min to 3 min. The high recovery rate (ranging from 99.91% to 101.8%) in actual serum detection suggests promising potential for practical applications. The development of bimetallic alloy heterojunctions presents new opportunities for creating efficient nanozymes.<\/jats:p>","DOI":"10.3390\/s24072242","type":"journal-article","created":{"date-parts":[[2024,3,31]],"date-time":"2024-03-31T13:32:56Z","timestamp":1711891976000},"page":"2242","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Using the Photo\u2013Piezoelectric Effect of AuPt@BaTiO3 Oxidase Mimetics for Colorimetric Detection of GSH in Serum"],"prefix":"10.3390","volume":"24","author":[{"given":"Yiquan","family":"Liao","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Yichang","family":"He","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Bin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Ye","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Ruiqi","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Minggang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]},{"given":"Hongzhi","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Ocean University of China, 266100 Qingdao, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131750","DOI":"10.1016\/j.snb.2022.131750","article-title":"Ultra\u2212fast colorimetric detection of glutathione by magnetic Fe NPs with peroxidase\u2212like activity","volume":"361","author":"Zhang","year":"2022","journal-title":"Sens.
