Soft Pneumatic Device Designed to Mimic the Periosteal Environment for Regulating the Fate of Mesenchymal Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a custom‐made soft pneumatic device (SPD) that mimics complex mechanical forces and fluid flow to enhance in vitro cell differentiation. It shows that low mechanotransduction promotes MSC differentiation into osteoprogenitor cells, while high mechanotransduction causes structural disruptions and cell detachment, providing new ...

Unlocking the Gates: A Novel Diagnostic Molecule for Quantifying Efflux Levels in Gram‐Positive Bacteria

open access: yesAdvanced Healthcare Materials, EarlyView.
Efflux‐mediated resistance compromises antibiotic efficacy, yet rapid detection remains elusive. This study presents a novel phenazinium‐based diagnostic molecule for quantifying bacterial efflux levels in Gram‐positive pathogens. The optimized compound enables precise, real‐time efflux assessment using fluorescence and colorimetric techniques ...

Polycations as Aptamer-Binding Modulators for Sensitive Fluorescence Anisotropy Assay of Aflatoxin B1

open access: yesSensors
Fluorescence induced by the excitation of a fluorophore with plane-polarized light has a different polarization depending on the size of the fluorophore-containing reagent and the rate of its rotation.

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Self‐Healing Hydrogel Dressing with Solubilized Flavonoids for Whole Layer Regeneration of Diabetic Wound

open access: yesAdvanced Healthcare Materials, EarlyView.
High glucose‐ and acid‐responsive hydrogel with dynamic covalent bond solubilized with flavonoids (Gel‐Flavonoids) is designed for diabetic wound healing. The Gel‐Flavonoids adapt to irregular wound shapes and release antioxidants in high‐glucose environments, effectively reducing reactive oxygen species.
