Between them, the prepared CNCs-doped hydrogels have not only a weak scattering structure that can provide excellent multiple scattering, thus yielding a large gain, but also good mechanical properties that can provide great advantages in the tuning of RL. The experimental results indicate that the RL emission wavelength blue shifts with an increase in the stretching length. The continuous tuning range reaches up to 7.1 nm when the CNCs-doped hydrogels are stretched to 400%. In addition, the proposed CNCs-doped hydrogels effectively solve the problem of the structures of traditional hydrogels, which are easily destroyed during repeated stretching and ensure good stability of RL output and tuning. The RL error is tested and found to be less than 0.5 nm, when the same length is stretched during repeated stretching. Our results provide a new approach to obtain tunable and stable RLs. Simultaneously, in combination with the good biocompatibility of CNCs-doped hydrogels, the proposed RLs demonstrated great importance in the biological field.","PeriodicalId":20108,"journal":{"name":"Photonic Sensors","volume":"15 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13320-025-0721-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147897315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we designed optical fiber biosensors by electrochemical polymerization to enable low detection limit (LOD) immunoassay. Based on the optical fiber lossy mode resonance (OF-LMR) achieved by In 2 O 3 -SnO 2 -90/10 wt% (ITO), we have simultaneously implemented the electropolymerized dopamine (ePDA) film on the ITO-coated fiber via the electrochemical method, utilizing the excellent electrical conductivity of ITO. After that, the immunoglobulin G (IgG) antibody layer was immobilized on the entire sensing region with the assistance of the ePDA film. The results of immunoassay were analyzed by recording the shift of the LMR resonance wavelength to verify the sensor performance. The LOD was evaluated as the lowest concentration of human IgG detected by the OF-LMR sensor, which was confirmed to be 4.20 ng·mL −1 . Furthermore, the sensor achieved selective detection for specific antigens and exhibited a good recovery capability in chicken serum samples. The developed scheme provides a feasible opportunity to enhance the intersection of electrochemistry and optics subjects and also offers a new promising solution to achieve the immunoassay.","PeriodicalId":20108,"journal":{"name":"Photonic Sensors","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13320-024-0714-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147891432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
