High-Performance Dielectric Modulated Epitaxial Tunnel Layer Tunnel FET for Label-Free Detection of Biomolecules

IEEE Open Journal of Nanotechnology
In this paper, using calibrated simulation we have reported a dielectric modulated epitaxial tunnel layer TFET (DM ETL-TFET) for the label-free detection of biomolecules. We have shown that due to vertical tunneling direction, the ETL-TFET exhibits $\sim$

Lateral Flow Aptasensor for Simultaneous Detection of Platelet-Derived Growth Factor-BB (PDGF-BB) and Thrombin

Molecules, 2019
Here we report a lateral flow aptasensor (LFA) for the simultaneous detection of platelet-derived growth factor-BB (PDGF-BB) and thrombin. Two pairs of aptamers, which are specific against PDGF-BB and thrombin, respectively, were used to prepare the LFA.

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

Advanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

Identification of sVSG117 as an immunodiagnostic antigen and evaluation of a dual-antigen lateral flow test for the diagnosis of human african trypanosomiasis [PDF]

, 2014
The diagnosis of human African trypanosomiasis (HAT) caused by Trypanosoma brucei gambiense relies mainly on the Card Agglutination Test for Trypanosomiasis (CATT). There is no immunodiagnostic for HAT caused by T. b. rhodesiense.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Harnessing the VO2 Phase Transition for Automatic Gain Control in Transimpedance Amplifiers

Advanced Electronic Materials, EarlyView.
A nanoscale VO2‐based volatile switch integrated into a transimpedance‐amplifier feedback loop dynamically lowers gain when input current rises, preventing saturation and extending dynamic range. Rapid self‐recovery restores high sensitivity without external reset circuitry.
