These limitations include susceptibility to environmental noise, a restricted dynamic range, and inadequate drift compensation. To address these issues, this work introduces a dual-core dual-channel micro-structured photonic crystal fiber (DC-DC-MPCF) sensor, which integrates independent detection and reference channels for simultaneous analyte detection and systematic error suppression. This sensor uses a molybdenum disulfide (MoS\n                    <jats:sub>2<\/jats:sub>\n                    ) excitation layer on a low-loss, water-resistant Zeonex substrate to boost plasmonic field localization and light-matter interactions. Structural innovations, such as a double-D-shaped polished platform and periodic airhole arrays, optimize evanescent field confinement and coupling efficiency between core-guided modes and surface plasmon polaritons (SPPs). Through finite element method (FEM) simulations, critical parameters such as residual cladding thickness (580 \u00b5m), ring cavity radius (140 \u00b5m), and MoS\n                    <jats:sub>2<\/jats:sub>\n                    layer thickness (10 \u00b5m) are rigorously optimized, achieving a maximum amplitude sensitivity of 162.1895 RIU\n                    <jats:sup>\u22121<\/jats:sup>\n                    and wavelength sensitivity of 98087.1 nm\/RIU. Simulations confirm that the dual channels operate independently, with the reference channel effectively compensating for environmental disturbances, achieving a wavelength resolution of 1.019 \u00d7 10\n                    <jats:sup>\u22126<\/jats:sup>\n                    RIU. The sensor demonstrates broad adaptability across a refractive index range of 1.33-1.45, enabling high-precision detection of trace biomolecules such as proteins and DNA. This work establishes a versatile platform for real-time, multi-analyte sensing applications in biomedical diagnostics and environmental monitoring.\n                  <\/jats:p>","DOI":"10.1364\/oe.581715","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T09:00:10Z","timestamp":1765357210000},"page":"54958","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Zeonex-MoS\n                    <sub>2<\/sub>\n                    hybrid dual-channel terahertz fiber biosensor for multi-analyte detection"],"prefix":"10.1364","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3524-3456","authenticated-orcid":true,"given":"Yunjie","family":"Ma","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02txfnf15","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shutao","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02txfnf15","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiangtao","family":"Lv","sequence":"additional","affiliation":[{"name":"Northeastern University at Qinhuangdao"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9666-4472","authenticated-orcid":true,"given":"Zhenghao","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02txfnf15","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinqing","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02txfnf15","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2025,12,23]]},"reference":[{"key":"oe-33-26-54958-R1","doi-asserted-by":"publisher","first-page":"194","DOI":"10.1364\/PRJ.508136","type":"journal-article","volume":"12","author":"Lyu","year":"2024","journal-title":"Photonics Res."},{"key":"oe-33-26-54958-R2","doi-asserted-by":"publisher","first-page":"2400077","DOI":"10.1002\/apxr.202400077","type":"journal-article","volume":"3","author":"Zhao","year":"2024","journal-title":"Adv.
