Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

Small, EarlyView.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Dual Quantum Dot Molecular FRET Probes for Picomolar DNA Hexaplexing

Small Methods, EarlyView.
Multiplexed quantification of six different DNA targets from a single 200 µL sample at picomolar concentrations was accomplished by spectrotemporal detection of time‐resolved FRET from a single Tb‐complex donor to two quantum dot acceptors using one‐color excitation and two‐color detection.

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

Tissue Factor‐High Ovarian Clear Cell Carcinoma Shows Immune‐Cold Features and Preclinical Activity of Tisotumab Vedotin

Cancer Science, EarlyView.
F3/TF‐high ovarian clear cell carcinoma exhibits an immune‐cold phenotype characterized by reduced immune‐cell fractions and attenuated cancer‐cell interferon programs, with frequent B7‐H4 co‐expression. Patient‐derived models show preclinical sensitivity to the TF‐directed antibody–drug conjugate tisotumab vedotin.
