A Microphase Separation‐Driven Supramolecular Tissue Adhesive with Instantaneous Dry/Wet Adhesion, Alcohol‐Triggered Debonding, and Antibacterial Hemostasis

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 21, 2025

Abstract Tissue adhesives are promising materials for expeditious hemorrhage control, while it remains a grand challenge to engineer superior formulation with instantaneous adhesion, on‐demand debonding, and the integration of multiple desirable properties such as antibacterial hemostatic capabilities. Herein, multifunctional supramolecular tissue adhesive based on guanidinium‐modified polydimethylsiloxane (PDMS) is introduced, driven by reversible microphase separation mechanism. By optimizing content guanidinium ions, precise control over cohesive strength, wettability achieved, resulting in strong adhesion under both dry wet conditions. Notably, nature allows convenient removal using medical‐grade alcohol, offering critical advantage easy debonding. Additionally, exhibits remarkable antimicrobial maintaining excellent biocompatibility hemocompatibility. Its underwater injectability supports minimally invasive surgical procedures. Furthermore, adhesive's ability incorporate solid particles enhances its versatility, particularly development drug‐embedded bioadhesives. This work addresses key challenges design via separation‐driven working principle, thereby opening new avenues advanced bioadhesives tailored enhanced wound care outcomes.
