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

open access: yesSmall, 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

open access: yesSmall 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 ...

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

open access: yesVIEW, 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 ...

Plant‐derived nanovesicles as potential drug delivery systems for topical use: Emerging applications in dermatology and cosmetology

open access: yesVIEW, EarlyView.
Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

Spatial Transcriptomics Identifies Characteristic Immunological Niches in Atopic Dermatitis

open access: yesAllergy, EarlyView.
Spatially organized immune niches containing mature migratory dendritic cells (mmDCs) and CD4+ T cells in atopic dermatitis lesions support localized T cell activation and may contribute to disease persistence. Spatial transcriptomics identifies conserved immune niches in atopic dermatitis lesions, characterized by close co‐localization of CD4+ T cells
