A Peptide Nucleic Acid‐Functionalized Heterojunction Thin Film Transistor as a Scalable and Reusable Platform for Label‐Free Detection of MicroRNA

Advanced Functional Materials, EarlyView.
A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

Advanced Functional Materials, EarlyView.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Biopolymer‐Templated Hierarchical 3D‐Structured Gold Nanoparticle/Graphene Oxide Hybrid Materials for Ultrasensitive Surface‐Enhanced Raman Scattering

Advanced Functional Materials, EarlyView.
A scalable bio‐templated approach using spray‐coating and thermal annealing fabricates cellulose nanofibril (CNF) films loaded with gold nanoparticles (Au NPs) and graphene oxide (GO) hybrids as Surface‐enhanced Raman scattering (SERS) substrates. The 3D CNF network ensures uniform Au NPs distribution, while annealing induces more hotspots, confirmed ...
