Aptamer Functionalized Hydrogel Dressings for Post‐Surgery Tumor Recurrence Inhibition and Tissue Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Post‐surgical tumor therapy struggles with recurrence and inefficient healing. Anti‐tumor DNA aptamer functionalized gelatin hydrogels, Apt‐GelMA, simultaneously address both issues by suppressing tumor regrowth via targeted tumor cell inhibition and enhancing wound healing through improved cell adhesion and migration. Their biocompatibility, stability,

Effect of Visco-Elasticity of an Orthotropic Arterial Wall on Pulse-Wave Propagation

open access: yesМеханика машин, механизмов и материалов, 2008
The problem of harmonic pressure wave propagation through a viscous fluid contained in a thin viscoelastic orthotropic tube is considered. To take into account viscoelasticity of the tube the linear viscoelasticity model is used.

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Supramolecular Liquid Crystal Elastomer Adhesives: Role of Internal Damping and Hydrogen Bonding

open access: yesAdvanced Functional Materials, EarlyView.
The adhesion strength can be significantly enhanced through the molecular design of supramolecular liquid crystal elastomers (LCEs) that combine high internal damping from mesogen reorientation with abundant hydrogen‐bonding moieties. Solvent vapor annealing enables reversible, non‐thermal control of adhesion, offering potential for heat‐sensitive ...

Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...
