Carbon dots in electrochemiluminescence: Mechanisms, interface engineering, and bioanalytical applications

Responsive Materials, EarlyView.
Carbon dots are emerging as versatile electrochemiluminescent nanomaterials whose structure, surface states, and interfacial design jointly determine ECL pathways and performance. This review highlights how mechanistic understanding and materials engineering enable programmable CD‐ECL systems for bioanalysis, imaging, and future intelligent analytical ...

Ultrasensitive MicroRNA Detection Combining Reduced Graphene Oxide Electrolyte‐Gated Transistors and Machine Learning

Small, EarlyView.
We developed an ultrasensitive and highly selective biosensor by integrating bio‐functionalized reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) and machine learning (ML) to detect miRNAs (miR‐34a, miR‐34b, and miR‐34c) associated with cancer and neurological disorders.

Nanopore and Self‐Assembled Monolayer Engineering of l‐Lactate Oxidase Gold Electrodes for Enhanced l‐Lactate Biosensing

Small, EarlyView.
A tiered nanoporous gold biointerface enables site‐directed immobilization of His‐tagged lactate oxidase through a mixed self‐assembled monolayer, achieving high enzyme loading while preserving activity. The resulting bioelectrode provides sensitive and stable l‐lactate detection (0.12–3.0 mM, 75 µA mM−1 cm−2), demonstrating a modular strategy for high‐

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

Small, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Bioelectronic Wearable Sensors Produced by Computerized Embroidery Using a Dual Thread Approach

Small, EarlyView.
A dual‐thread embroidered SmartBra integrates silver‐plated and conductive‐polymer (PECOTEX) threads to enable simultaneous cardiac monitoring and open‐circuit potentiometric sensing of potassium and sodium in a breast milk substitute. The wearable platform is fabricated using computerized embroidery, offering a scalable, proof‐of‐concept route toward ...
