Multifunctional Wound Dressings: Melt Electrowritten Scaffolds Combined With Phytotherapeutic Composite Hydrogels

Advanced Materials Interfaces, EarlyView.
ABSTRACT The increasing prevalence of impaired wounds, caused mainly by diabetes or aging, alongside the growing number of bacterial infections, indicates the need for alternative tissue engineering solutions. In this study, we developed novel melt electrowritten (MEW) polycaprolactone (PCL) scaffolds incorporated with an alginate (Alg)–gelatin (Gel ...

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

Advanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

INTERCALATION OF FREE RADICAL, DPPH, INTO MONTMORILLONITE

Analytical Sciences, 1991
The adosorption of DPPH in the interlayer of sodium montmorillonite and sodium saponite have been investigated by ESR. As the results, DPPH molecules dimerize to form diamagnetic species in montmorillonite, whereas DPPH molecules in saponite exist as isolated stable free radical species at room temperature.

Stage‐Adaptive Janus Microneedle System for Redox‐Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing

Advanced Science, EarlyView.
ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...
