Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

Advanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

On the Molecular Diffusion Dynamics Between Subcutaneous Tissue and Microneedles for Wearable Continuous Glucose Monitoring

Advanced NanoBiomed Research, EarlyView.
In this study, we investigate the dynamics of glucose diffusion between subcutaneous tissue and hydrogel‐filled microneedles. Specifically, we examine how hydrogel thickness, microneedle size, and glucose concentration influence diffusion. This study provides an experimental reference to the wearable biosensor community researching microneedle‐based ...

Mechanically Induced Switching Between Orbital‐ and Fano‐Resonance Rectification in a Dual‐Anchored Molecular Junction

Angewandte Chemie International Edition, EarlyView.
Mechanical control of anchoring chemistry enables switching between orbital‐driven and interference‐driven rectification in a single‐molecule junction. ABSTRACT Achieving precise control over charge transport through individual molecules is central to advancing single‐molecule electronics.

Magnetic Field‐Modulated Boolean Logic in Proteinoid‐ Fe3 O4 Hybrid Materials

Advanced Physics Research, EarlyView.
Proteinoid‐Fe3O4${\rm Fe}_3{\rm O}_4$. nanoparticle composites exhibit spontaneous electrical oscillations that emulate Boolean logic gates (AND, OR, XOR, NAND, NOR, NOT) under magnetic field modulation. External fields of 65.103 mT tune oscillatory behavior: 84 mT enhances amplitude while 103 mT suppresses it.
