Signal-enhanced multi-core fiber-based WaveFlex biosensor for ultra-sensitive xanthine detection

Optics Express, Год журнала: 2023, Номер 31(26), С. 43178 - 43178

Опубликована: Ноя. 28, 2023

In this work, we introduce a novel multimode fiber (MMF) – seven core (SCF) MMF (MCM) optical biosensor, also known as the WaveFlex biosensor (plasma wave assisted biosensor), based on localized surface plasmon resonance (LSPR) for qualitative detection of xanthine. Xanthine is purine base widely distributed in human blood and tissues, commonly used an indicator various disease detections. The MCM sensor incorporates tapered structure, fabricated using combiner manufacturing system (CMS), designed with SCF MMF. By effectively harnessing LSPR, boosts attachment points biomolecules probe through immobilized tungsten disulfide (WS 2 )-thin layers, gold nanoparticles (AuNPs), carbon nitride quantum dots (C 3 N-QDs). functionalization xanthine oxidase (XO) sensing further enhances sensor's specificity. proposed exhibits remarkable sensitivity 3.2 nm/mM low limit 96.75 µM within linear range 100 - 900 µM. Moreover, demonstrates excellent reusability, reproducibility, stability, selectivity. With its sensitivity, biocompatibility, immense potential detecting serum fish products, presents promising platform future applications.

An Electrochemical Immunosensor Based on Chitosan–Graphene Nanosheets for Aflatoxin B1 Detection in Corn

Molecules, Год журнала: 2024, Номер 29(7), С. 1461 - 1461

Опубликована: Март 25, 2024

We reported a highly efficient electrochemical immunosensor utilizing chitosan–graphene nanosheets (CS-GNs) nanocomposites for the detection of aflatoxin B1 (AFB1) in corn samples. The CS-GNs nanocomposites, serving as modifying layer, provide significant specific surface area and biocompatibility, thereby enhancing both electron transfer rate efficiency antibody immobilization. characterization was conducted differential pulse voltammetry (DPV) impedance spectroscopy (EIS). Moreover, concentration, pH, immobilization time, immunoreaction were optimized. results showed that current change (ΔI) before after demonstrated strong linear relationship (R2=0.990) with AFB1 well good specificity stability. range extended from 0.05 to 25 ng/mL, limit 0.021 ng/mL (S/N=3). exhibited recovery ranging 97.3% 101.4% samples, showing promising performance using an method, indicating remarkable prospect fungal toxins grains.

IEEE Sensors Journal, Год журнала: 2023, Номер 24(4), С. 4480 - 4487

Опубликована: Дек. 29, 2023

Alpha-fetoprotein (AFP), a biomarker for liver cancer detection, has important clinical significance. Here, an S-tapered WaveFlex fiber biosensor is developed that based on the structure of multimode (MMF)–multicore (MCF)–MMF and leaks more energy when excited by light. ZnO nanowires (ZnO-NWs)/WS2 nanosheets (WS2-NSs) gold nanoparticles (AuNPs) are functionalized probe surface to further enhance sensing performance. 1-D ZnO-NWs possess larger specific area can provide sites antibodies. The fold WS2-NSs provides ample space functionalization. combination above two nanomaterials conducive immobilization AuNPs AFP antibodies improves performance biosensor. used generate localized plasmon resonance (LSPR) specificity probe, respectively. employed detect solution in range 0–1000 ng/mL, sensitivity limit detection (LoD) obtained as 1.32 nm/log(ng/mL) 84 pg/mL, Moreover, practical application capability verified selectivity test, pH reproducibility, reusability experiments. results demonstrate potential sensor markers.
