However, challenges related to the fabrication and stability of ZnO nanostructures on biocompatible materials such as organic polymers limit biomolecule detection. Here, an 8-well strip ZnO nanosubstrate was developed using a one-step integration fabrication process to overcome the challenges, in which ZnO nanoparticles (NPs) were combined with polypropylene (PP) pellets; the hydrothermal synthesis of ZnO NWs was then performed under controlled heating and agitation conditions. The suitable ZnO NP concentration was determined to create a robust seed layer, thereby forming sea-urchin-shaped ZnO NW structures. Further characterization revealed enhanced biomolecule binding efficiency, reduced autofluorescence, and stability of ZnO nanostructures after a 5 h ZnO NW growth period. This ZnO nanosubstrate was the basis for the development of a highly sensitive immunoassay for Mycobacterium tuberculosis antigen (Mycobacterium protein tuberculosis 64 [MPT64]) detection. In experiments with the recombinant MPT64, our ZnO nanosubstrate-well strip-based assay showed a significantly lower limit of detection (0.977 pg\/mL) than conventional immunoplates (62.5 pg\/mL) and commercial lateral flow assays (1 ng\/mL). The clinical relevance of the ZnO nanosubstrate well strip-based immunoassay was validated by its ability to reliably distinguish between cultured sputum samples from patients with tuberculosis (TB) and those from patients with non-tuberculous mycobacterial infection or negative control subjects. Accordingly, the proposed 8-well strip ZnO nanosubstrate offers a highly reliable platform for immunoassay development, providing enhanced sensitivity and robust performance for TB diagnostics and broader biomolecule detection applications.<\/jats:p>","DOI":"10.1021\/acsabm.6c00911","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T04:21:16Z","timestamp":1788409276000},"page":"8568-8579","source":"Crossref","is-referenced-by-count":0,"title":["Development of Stable Nanosubstrates Using ZnO Nanoparticle-Embedded Polymer Composites for Sensitive Detection of MPT64 Antigens"],"prefix":"10.1021","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8976-0062","authenticated-orcid":true,"given":"Jung","family":"Kim","sequence":"first","affiliation":[{"name":"Korea Research Institute of Chemical Technology , , ,","place":["Daejeon, Republic of Korea, 34114"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In Young","family":"Yoo","sequence":"additional","affiliation":[{"name":"Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea , , ,","place":["Seoul, Republic of Korea, 06591"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6541-6272","authenticated-orcid":true,"given":"Yujin","family":"Jung","sequence":"additional","affiliation":[{"name":"Korea Research Institute of Chemical Technology , , ,","place":["Daejeon, Republic of Korea, 34114"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joo An","family":"Kwon","sequence":"additional","affiliation":[{"name":"Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea , , ,","place":["Seoul, Republic of Korea, 06591"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeon-Joon","family":"Park","sequence":"additional","affiliation":[{"name":"Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea , , ,","place":["Seoul, Republic of Korea, 06591"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4380-3551","authenticated-orcid":true,"given":"Hong Gi","family":"Kim","sequence":"additional","affiliation":[{"name":"Korea Research Institute of Chemical Technology , , ,","place":["Daejeon, Republic of Korea, 34114"]},{"name":"Korea University of Science and Technology , , 141 Gajeong-ro, Yuseong-gu , ,","place":["Daejeon, Republic of Korea, 34114"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"issue":"25","key":"2026092100082464400_cit1","doi-asserted-by":"publisher","DOI":"10.1088\/0953-8984\/16\/25\/R01","article-title":"Zinc oxide nanostructures: growth, properties and applications","volume":"16","author":"Wang","year":"2004","journal-title":"J.
