Charge balance transition enabled Janus hydrogel for robust wet-tissue adhesion and anti-postoperative adhesion

Bioactive Materials
Janus hydrogels have recently emerged as promising bioadhesives for efficient wet-tissue adhesion and anti-postoperative adhesion. However, existing Janus hydrogel adhesives normally need varied chemical designs of different layers to achieve asymmetric ...

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Mechanically Reinforced Catechol-Containing Hydrogels with Improved Tissue Gluing Performance

Biomimetics, 2017
In situ forming hydrogels with catechol groups as tissue reactive functionalities are interesting bioinspired materials for tissue adhesion. Poly(ethylene glycol) (PEG)–catechol tissue glues have been intensively investigated for this purpose.

Fibrin versus polyethylene glycol sealant: an experimental study in rabbits [PDF]

, 2018
Fibrin glue has been applied universally in general surgery as an adhesive, hemostatic, or embolizing agent. In reconstructive surgery, fibrin has been used mainly for nerve and microvascular repair or as a substitute for sutures in skin closure and skin

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

Advanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

Wet tissue adhesive polymeric powder hydrogels for skeletal muscle regeneration

Bioactive Materials
Volumetric muscle loss (VML) frequently results from traumatic incidents and can lead to severe functional disabilities. Hydrogels have been widely employed for VML tissue regeneration, which are unfortunately ineffective because of the lack of intimate ...

Dual‐Network Protein Hydrogels Promote Rapid Hemostasis and Immune‐Regulated Scarless Tissue Regeneration

Advanced Science, EarlyView.
A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.
