Lipopolysaccharide‐Specific Aptasensor: A Spectroscopic Approach for Identifying Gram‐Negative Bacteria

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
We developed a novel aptasensor by integrating an anti‐lipopolysaccharide aptamer with a G‐quadruplex DNAzyme for the detection of Gram‐negative bacteria. This label‐free, spectroscopy‐based sensor detects E. coli with a limit of ∼2.7 × 105 cells/mL, providing a rapid, cost‐effective and specific method for identifying LPS‐containing bacteria ...

Dual‐Spectrum Fluorescence Quenching of Aggregation‐Induced Emission Nanoparticles for Dual‐Signal Lateral Flow Immunoassay of Danofloxacin in Meat Samples

open access: yesFood Frontiers, Volume 7, Issue 6, November 2026.
ABSTRACT The conventional gold nanoparticle‐based lateral flow immunoassay (AuNPs‐LFIA) is hampered by single colorimetric signal readout and insufficient sensitivity, restricting its broad application in trace detection for food safety. Herein, an AuNPs‐triggered dual‐spectrum fluorescence quenching LFIA (DSFQ‐LFIA) was constructed for colorimetric ...

Serum Neurofilament Light Chain and GFAP in Amyotrophic Lateral Sclerosis on a Commercial ECLIA Platform

open access: yesMuscle &Nerve, Volume 74, Issue 5, Page 1398-1405, November 2026.
ABSTRACT Introduction/Aims In amyotrophic lateral sclerosis (ALS), SIMOA‐based studies show that baseline serum neurofilament light chain (NfL) predicts the revised ALS Functional Rating Scale (ALSFRS‐R) decline rate and survival. The Roche Elecsys electrochemiluminescence immunoassay (ECLIA) reports values approximately six‐fold lower; cross‐platform ...

Detection of Mycobacterium avium subsp. paratuberculosis in Bovine Faeces Using a Rhodamine B Hydrazone Immunosensor on Antibody‐Coated Nitrocellulose Membranes

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A rhodamine B hydrazone nanoparticle‐based immunosensor coupled with an antibody‐coated nitrocellulose membrane (IMS‐CNM) was developed for rapid detection of Mycobacterium avium subsp. paratuberculosis (MAP) in bovine faeces. The assay combines antibody‐mediated bacterial capture with chromogenic nanoparticle detection, providing a simple, rapid and ...

Oral Contraceptive Use Is Associated With Increased Tenderness to Palpation in the Masticatory System in Female Adolescents—Results of the Epidemiological LIFE Child Study

open access: yesJournal of Oral Rehabilitation, Volume 53, Issue 11, Page 2158-2165, November 2026.
The use of OC has been demonstrated to enhance the likelihood of encountering self‐reported headaches and increased tenderness to palpation within the masticatory system in female adolescents. ABSTRACT Background The utilisation of oral contraceptives (OCs) has been demonstrated to be associated with the self‐reported occurrence of headaches in female ...

Model‐Guided Design of Paper Membrane Architectures for Controlled Flow and Enhanced Diagnostic Sensitivity

open access: yesAdvanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
Geometrical modifications on nitrocellulose membranes can result in observable differences in signal intensity relative to a reference membrane (top and bottom left). Using two reference experiments, we have developed a theoretical model that can reproduce the experimentally observed flow changes and provide information on membrane parameters, e.g ...
