Book Description
The coexistence of anions and cations in zwitterionic hydrogels results in electrostatic interactions between the polymer chains. This structure endows zwitterionic hydrogels with higher ion sensitivity and promising properties, such as anti-polyelectrolyte and thermosensitive effects. Hydrophilic groups on the molecular backbone give zwitterionic hydrogels good biocompatibility, and they effectively resist the non-specific adsorption of proteins. The abundant functional groups on the molecular skeleton also facilitate the chemical modification of zwitterionic hydrogels. In recent years, these excellent properties have made zwitterionic hydrogels broadly interesting and they have been heavily studied for medical applications. A comprehensive review will help researchers have a deeper understanding of zwitterionic hydrogels and their potential applications. In this review, the types, functional characteristics, and applications in the biomedicine of zwitterionic hydrogels are summarized in detail. In addition, the challenges and opportunities for using zwitterionic hydrogels for biomedical applications are discussed.

Book Description
Hydrogels, as three-dimensional polymer networks, are able to retain a large amount of water in their swollen state. The biomedical application of hydrogels was initially hampered by the toxicity of cross-linking agents and the limitations of hydrogel formation under physiological conditions. However, emerging knowledge in polymer chemistry and an increased understanding of biological processes have resulted in the design of versatile materials and minimally invasive therapies.The novel but challenging properties of hydrogels are attracting the attention of researchers in the biological, medical, and pharmaceutical fields. In the last few years, new methods have been developed for the preparation of hydrophilic polymers and hydrogels, which may be used in future biomedical and drug delivery applications. Such efforts include the synthesis of self-organized nanostructures based on triblock copolymers with applications in controlled drug delivery. These hydrogels could be used as carriers for drug delivery when combined with the techniques of drug imprinting and subsequent release. Engineered protein hydrogels have many potential advantages. They are excellent biomaterials and biodegradables. Furthermore, they could encapsulate drugs and be used in injectable forms to replace surgery, to repair damaged cartilage, in regenerative medicine, or in tissue engineering. Also, they have potential applications in gene therapy, although this field is relatively new.
