However, fewer work has focused on the long non-coding RNAs (lncRNAs) sensing, which are most likely present in ISF and engage in the occurrence and development of Alzheimer's disease (AD). In this work, taking adenocarcinoma transcript 1 (MALAT1) as the representative of lncRNAs, which is abnormally down-regulated in AD patients, a robust hydrogel MN array - based fluorescent patch was developed for MALAT1 by integrating a methacrylated gelatin (GelMA) hydrogel MN as the extraction tool with a strand displacement reaction (SDR) mediated fluorescent probe. Specifically, the MNs were prepared by the simple and feasible photo-crosslinking of GelMA, which displayed satisfactory swelling capability for extracting ISF and mechanical strength to penetrate the skin's cuticle layer. Subsequently, a triplex SDR amplification probe was constructed for MALAT1 sensing. By mixing with the prepolymer solution, the MNs patch loaded with the fluorescent probe was fabricated, which demonstrated excellent sensing performances in both PBS and agarose simulated skin, with lower limits of quantification (LLOQ) of 7.62 and 13.24 nM, respectively. The developed MN patch was proved highly suitable for distinguishing the down-regulated MALAT1 expressions in ISF of AD mice. This work represented the first example to correlate the changes in the levels of MALAT1 in ISF with AD pathology, providing a practical tool for the early non - invasive diagnosis of AD.</div></div>","PeriodicalId":259,"journal":{"name":"Biosensors and Bioelectronics","volume":"288 ","pages":"Article 117823"},"PeriodicalIF":10.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144702248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, TO/CIS/CdS showed excellent PEC and ECL dual signals, which was applied to dual-mode sensing and detection. By using cyclic amplification and magnetic separation techniques, target ENR was converted into a large number of product chains with ZnO nanoparticles (NPs), and acidolysis was carried out to obtain zinc ions. Then, a layer of supramolecular hydrogel with good biocompatibility and stability was formed on the electrode using the ligand interaction between adenosine monophosphate (AMP) and Zn<sup>2+</sup>. The poor electrical conductivity and light transmission of the hydrogel layer make it an excellent double-quenching material for PEC and ECL signals, which was used for sensitive dual-mode detection of ENR. The cyclic amplification technique in a homogeneous solution was utilized to improve the sensitivity of detection while avoiding the complex electrode-modification process, thus effectively improving efficiency and stability of the sensor.

Herein, we designed an ultrasensitive biosensor leveraging MOFs as a multifunctional nano-platform to implement a synergistic self-calibration strategy for the ultra-accurate quantification of breast cancer-related human epidermal growth factor receptor-2 (HER-2). This approach integrates (1) ratiometric electrochemistry for built-in correction to minimize non-specific interference and (2) dual-modal electrochemical and colorimetric detection for enhanced accuracy through cross-validation. Functionalized NH<sub>2</sub>-UiO-66 (Zr-MOF) was employed as a carrier to incorporate a dual-layer of anthraquinone-2-carboxylic acid (AQ), creating NH<sub>2</sub>-UiO-66@AQ, a highly electroactive nanomaterial for signal amplification.
