Nature-Inspired Gelatin-Based Adhesive Hydrogel: A Rapid andUser-Friendly Solution for Hemostatic Applications.
Advanced Healthcare Materials 2024 March 28
Conventional hemostatic agents face challenges in achieving rapid hemostasis and effective tissue repair due to limited hemostatic scenarios, suboptimal efficacy, and inadequate adhesion to wet tissues. Drawing inspiration from nature-sourced materials, we designed a gelatin-based adhesive hydrogel (AOT), easily prepared and quick to form, driven by Schiff base and multiple hydrogen bonds for applications in arterial and liver bleeding models. AOT exhibited exceptional adhesion to wet tissues (48.67 ± 0.16 kPa) and displays superior hemostatic properties with reduced blood loss and hemostatic time compared to other hydrogels and conventional hemostatic materials. Moreover, AOT hydrogel exhibited good biocompatibility and biodegradability. In summary, this easily prepared adhesisve hydrogel has the potential to supplant traditional hemostatic agents, offering a novel approach to achieve swift sealing of hemostasis and facilitate wound healing and repair in broader application scenarios, owing to its unique advantages.
