Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

open access: yesAdvanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

Interfacial Bioengineering of Dynamic Networks Hybrid Hydrogel for Programmed Intervention in Oral Precancerous Epithelial States

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a dual‐bioinspired hydrogel, MSA@PGel (macrophage membrane‐coated and salvianolic acid B/5‐aminolevulinic acid co‐loaded liposomes embedded in a polydopamine‐based gel), that integrates macrophage membrane‐mediated active targeting and mussel‐inspired wet adhesion for programmed intervention in oral precancerous lesions.

In Vivo Skin 3‐D Surface Reconstruction and Wrinkle Depth Estimation Using Handheld High Resolution Tactile Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
A compact handheld GelSight probe reconstructs in vivo 3‐D skin topography with micron‐level precision using a custom elastic gel and a learning‐based surface normal to height map pipeline. The device quantifies wrinkle depth across various body locations and detects changes in wrinkle depth following moisturizer application.

The Promise of Solid Lubricants for a Sustainable Future

open access: yesAdvanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?
