A Current Conveyor Implementation of Double Differential Amplifier for Active Electrodes

open access: yesInternational Journal of Circuit Theory and Applications, Volume 54, Issue 10, Page 5019-5029, October 2026.
A CCII‐based electronic architecture for surface electromyography (sEMG) signal acquisition is presented. Simulations results demonstrate its potential as an effective analog front‐end for biomedical monitoring applications. ABSTRACT This work presents two transistor‐level solutions to implement a double differential (DD) amplifier by using a current ...

Painless Biosensing for Non‐Invasive Health Monitoring: Advances, Platforms and Future Directions

open access: yesElectrochemical Science Advances, Volume 6, Issue 5, October 2026.
ABSTRACT Non‐invasive biosensing has expanded blood‐based diagnostics into a growing set of accessible peripheral biofluids, yet most existing reviews remain confined to sweat, tears, saliva and urine, and treat the underlying literature descriptively rather than critically.

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,

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

open access: yesSmall, Volume 22, Issue 56, 8 October 2026.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Selective and Fast Cortisol Sensing in Human Saliva Using Graphene‐Based On‐Chip Field‐Effect Transistors

open access: yesSmall Science, Volume 6, Issue 10, October 2026.
Electrolyte‐gated graphene field‐effect transistors (EG‐GFETs) functionalized with anticortisol Fab fragments enable rapid, label‐free detection of cortisol in human saliva within 10 min. Sensitive operation in physiologically relevant media, together with direct validation against ELISA, demonstrates the potential of this platform for future portable ...
