Laser‐Induced Graphene/AuNPs‐Gated OECT Biosensor for Sensitive Detection of PD‐L1‐Positive Exosomes Associated With Non‐Small Cell Lung Cancer

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lung cancer remains a major cause of cancer‐related mortality worldwide, and non‐small cell lung cancer (NSCLC) accounts for the largest proportion of diagnosed lung cancer cases. Exosomal programmed death‐ligand 1 (PD‐L1) has attracted increasing attention as a potential liquid‐biopsy biomarker associated with tumor immune regulation; however,

Modular Metalloprotein Nanowires With Semiconductor‐Scale Conductivity and Tunable Redox Behavior

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
Conductive protein nanowires are built by aligning three different metalloproteins along an ultrastable filament scaffold. The resulting micrometer‐length nanowires reach conductivities of 1.75 S cm−1. Redox behavior is set by the metalloprotein chosen, while conductivity is governed by the spacing the scaffold imposes, making both independently ...

Deletion of the sodium leak channel NALCN in dopamine neurons alters D2R‐mediated signalling and psychostimulant responsiveness

open access: yesThe Journal of Physiology, Volume 604, Issue 20, Page 8542-8568, 15 October 2026.
Abstract figure legend The sodium leak channel NALCN is an important contributor to the spontaneous pacemaker activity of midbrain dopamine neurons and is required for proper presynaptic D2 autoreceptor signalling at dopaminergic terminals. Conditional deletion of NALCN in dopamine neurons enhances psychomotor sensitization to amphetamine and cocaine ...

Ratiometric pH‐Responsive and Biomimetic Microparticles for Quantitative Monitoring of Phagosomal Acidification

open access: yesChemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
A series of hydrosoluble BODIPY pH probes allows building biomimetic pH sensors based on micrometric oil‐in‐water droplets. The ratiometric fluorescence output offers quantitative information on the evolution of pH during phagosome maturation. ABSTRACT We present a modular biomimetic fluorescent sensing platform designed to precisely interrogate the ...

Aptamer-based lateral flow assay on-site biosensors

Biosensors and Bioelectronics, 2021
The lateral flow assay (LFA) is a widely used paper-based on-site biosensor that can detect target analytes and obtain test results in several minutes. Generally, antibodies are utilized as the biorecognition molecules in the LFA. However, antibodies selected using an in vivo process not only may risk killing the animal hosts and causing errors between

Numerical prototyping of lateral flow biosensors

open access: yesSensors and Actuators B: Chemical, 2018
Abstract Lateral flow biosensors (LFB) have become a hot topic in the scientific literature in association with the rapid growing of paper-based microfluidics. Improving the existing LFB technology is a challenging task that demands large experimental efforts.
