Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Tailored Polymer‐Based SEI via iCVD for Stable Zinc Metal Anodes in Aqueous Batteries through Modulation of Hydrophilicity and Elasticity to Inhibit Hydrogen Evolution Reactions

Advanced Functional Materials, EarlyView.
A stretchable and superhydrophobic pF1V1 polymer layer is conformally coated on Zn metal via iCVD, forming a water‐repelling interphase that inhibits the hydrogen evolution reaction. This tailored interface maintains excellent electrolyte compatibility while suppressing dendrite growth, thereby enhancing the long‐term electrochemical stability of Zn ...

Heterostructured Sn:SnO2 Nanodots for High‐Performance Li–S Batteries with Kinetics‐Enhanced Cathode and Dendrite‐Free Anode

Advanced Functional Materials, EarlyView.
Heterostructured Sn:SnO2 nanodots decorated on reduced graphene oxide can simultaneously enhance conversion kinetics and inhibit dendrite growth, enabling stable lithium–sulfur batteries. Abstract The practical application of lithium–sulfur batteries is limited by polysulfide shuttling and sluggish reaction kinetics at the cathode, as well as ...

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

Advanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

Fluorophobic Effect Enables Selective Detection of PFAS in Water with Electrolyte‐Gated Organic Transistors

Advanced Functional Materials, EarlyView.
PerFluoroAlkyl Substances (PFAS) are responsible of major and persistent environmental pollution worldwide. This work demonstrates an ultra‐sensitive sensor for PFAS based on an organic transistor whose gate is functionalized with a binary self‐assembled monolayer containing a perfluorinated molecule.
