Through optimization of the material synthesis process, the optimal doping ratio of MoS2 to Ni3+ (70% MoS2 and 10% Ni3+) was identified, which significantly enhanced the photogenerated carrier separation efficiency. In thin-film preparation, comparative analysis of four film-forming methods led to the determination of an optimal process with stability. To achieve highly specific CAP detection, the nanocomposite chip was integrated with nucleic acid aptamer biorecognition elements within a standard three-electrode detection system. Experimental results demonstrated a linear response (R2 = 0.998) in the 0.1\u20132 \u03bcM concentration range, with a detection limit of 3.69 nM (3\u03c3\/S).<\/jats:p>","DOI":"10.3390\/bios15070454","type":"journal-article","created":{"date-parts":[[2025,7,15]],"date-time":"2025-07-15T09:45:52Z","timestamp":1752572752000},"page":"454","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ultra-Sensitive Detection of Chloramphenicol by CdS@NiMoS Nanorods-Based Photoelectrochemical Aptasensor"],"prefix":"10.3390","volume":"15","author":[{"given":"Hebin","family":"Sun","sequence":"first","affiliation":[{"name":"State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yimeng","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Qi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenyu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianlong","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, China"},{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijuan","family":"Liang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, China"},{"name":"Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1016\/j.etap.2014.11.016","article-title":"Antibiotics Exposure and Health Risks: Chloramphenicol","volume":"39","author":"Hanekamp","year":"2015","journal-title":"Environ.
