Peptide‐based responsive molecular fluorescent probes for precision oncology

Responsive Materials, EarlyView.
Peptide‐based responsive fluorescent probes have emerged as adaptive functional materials for precision tumor theranostics, combining tumor‐selective recognition, programmable stimulus responsiveness, and modular tunability. They enable high‐contrast imaging, intraoperative guidance, real‐time monitoring, and multimodal applications, while next ...

Supramolecular Chiral Assembly of Open‐Shell Quinoids With Chiral Additives and Their Spin‐Dependent Transport in Magneto Field‐Effect Transistors

Small, EarlyView.
Open‐shell quinoids with intrinsic spins are assembled into chiral supramolecular structures via blending with chiral additives. Thermal annealing induces stable co‐crystallization, leading to a 30‐fold amplification of chirality (gabs = 1.23 × 10−2). Significantly, this study represents the first integration of spin‐possessing chiral assemblies into ...

Glucose Amperometric Biosensor Based on the Co-immobilization of Glucose Oxidase (GOx) and Ferrocene in Poly(pyrrole) Generated from Ethanol / Water Mixtures

Journal of the Brazilian Chemical Society, 2001
The co-immobilization of GOx and ferrocene in a polymeric matrix by a one-step simple method is presented. This procedure to immobilize ferrocene as mediator implies the absence of modification of the monomer or the enzyme that would lead to the loss of ...

Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

Small, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...

Oxophilic Yb2O3 nanoparticles as radical scavengers to enhance the durability of Fe–N–C oxygen reduction catalysts

Smart Molecules, EarlyView.
Fe–N–C catalysts suffer from radical attack during oxygen reduction. By immobilizing oxophilic Yb2O3 nanoparticles near Fe–N4 sites as efficient radical scavengers, the catalyst achieves enhanced activity and stability. Abstract The practical application of Fe–N–C catalysts in proton exchange membrane fuel cells is substantially limited by their ...

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, EarlyView.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

A N,N′‐p‐Tolyl Substituted Diazadiene Ligand with a Dithienylethane Backbone in Hexacoordinated Group IV Tetrachlorido Complexes—Steric Repulsions Govern the Axial Chirality Mode

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The chelating imino groups in [MCl4(DADDTEthane)] (M = Ti, Zr, Hf) give rise to a planar five‐membered (‐N=C‐C=N‐)M metallacycle. The two thiophene rings of the ligand backbone reside in a noncoplanar arrangement concerning the metallacycle, giving rise to two chiral C–C axes in the ligand backbone.
