Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

open access: yesAdvanced Materials, EarlyView.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

Short‐Wavelength Infrared Imaging with Organic Photodetectors Based on Non‐Fullerene Acceptors with Detection above 1200 nm

open access: yesAdvanced Materials, EarlyView.
Solution‐processed organic photodetectors (OPDs) based on two novel low band gap non‐fullerene acceptors BZIC‐2F and BZIC‐2Cl, when blended with common polymer donor P3HT, extend detection range beyond 1200 nm with superior performance, rivaling costly inorganic sensors and past literature.

Bioelectrical Interfaces Beyond Excitable Cells: Cancer, Aging, and Gene Expression Modulation

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT The investigation of biological conductivity has evolved from its classical foundation based on ionic fluxes underpinning cardiac and neuronal excitability to a multifaceted regulator of cellular physiology. Traditional approaches for probing electrical events in living matter focused largely on action potentials recording.

Killing arthritogenic fibroblast-like synoviocytes: an example using cytotoxic aptamers binding nucleolin

open access: yesArthritis Research & Therapy
“Pauci-immune” and “fibroblast-rich” synovial pathotypes are predictors of resistance to multi-drug immunosuppression. For these “difficult-to-treat” (D2T) endotypes of rheumatoid arthritis (RA), depletion of arthritogenic fibroblast-like synoviocytes ...

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

open access: yesAdvanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐
