Dual‐Atom Catalyst Au@S‐rGO for Rapid and Highly Sensitive Electrochemical Detection of Fentanyl in Serum

open access: yesAdvanced Science, EarlyView.
This study develops an Au/S‐doped reduced graphene oxide (Au@S‐rGO) sensor for rapid fentanyl detection. DFT simulations and structural analysis confirm atomically dispersed Au/S configurations, enhancing catalytic activity. The sensor achieves a 9.7 nmol L−1 detection limit, 98–104% recovery in human serum, and 85.7–93.6% consistency with mass ...

Vermicular Eutectic Multi‐Principal Element Alloy with Exceptional Strength and Ductility

open access: yesAdvanced Science, EarlyView.
Eutectic multi‐principal element alloys (EMPEAs) typically exhibit rod‐like or lamellar microstructures, constraining further mechanical improvements. This study introduces a novel (AlCrFe2)65Ni35 EMPEA with a unique vermicular microstructure, achieving unprecedented strength‐ductility synergy.

Flexible Optoelectronic Hybrid Microfiber Long‐period Grating Multimodal Sensor

open access: yesAdvanced Science, EarlyView.
An entirely new optoelectronic hybrid multimodal optical fiber sensor which can simultaneously monitor biomechanics and glucose is demonstrated. The developed method simultaneously integrates two heterogeneous sensing mechanisms, optical and electrical, into a single sensor in a compact manner. Optical and electrical sensors can work simultaneously but

A Touch Enabled Hemodynamic and Metabolic Monitor

open access: yesAdvanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Implementing Multimodal Hardware Security with 2D α‐In2Se3 Ferroelectric Transistor

open access: yesAdvanced Science, EarlyView.
A multimodal secure transistor‐integrated in‐memory sensing and computing architecture is demonstrated by leveraging its electronic and optoelectronic synaptic behaviors. Key security primitives, such as anticounterfeiting, watermarking, logic locking, and camouflaging, are implemented within a compact single‐transistor structure, providing a scalable ...
