Mechanisms and promising applications of mussel-inspired hydrogels

mussel-inspired chemistry has become a powerful tool for the rational design and synthesis of hydrogels with modified properties and applications due to their unique functionalities. Hydrogels are cross-linked three-dimensional polymer networks with high water content and flexible structure, and due to their mechanical and chemical similarities with biological tissues, as well as the existence of mechanical and electrical properties, they are used in various fields of medical engineering, soft robotics, Electronics and environmental science have many applications. Despite the extensive progress in this field, conventional hydrogels still face many problems, such as the lack of general strategies to program the chemical/physical properties and the difficulty in meeting some specific application requirements, especially in the diverse and complex working environment that limit their application. severely restricts. Therefore, the modification of hydrogels according to different purposes can lead to their more and better use in various industries. Adhesive hydrogels are gaining interest for biomedical applications due to their high adhesion, tunable structure, high water content, and biocompatibility. Meanwhile, the modification of normal hydrogels with the help of oyster-inspired chemistry, such as the use of dopamine and tannic acid, can give unique properties to the gels and their application in many fields, including biomedical engineering, electronics, stimuli and sensors. Wider wearable. Our aim in this review article is to investigate the hydrogel made with the help of mussel-inspired compounds.
