A hydrogel is a biphasic material, a mixture of porous and permeable solids and at least 10% of water or other interstitial fluid. [1][2] The solid phase is a water insoluble three dimensional network of polymers, having absorbed a large amount of water or biological fluids. [2][3][4][5] Hydrogels have several applications, especially in the bio...

2022年11月21日 · hydrogel: A “smart” material that can change its structure in response to its environment, such as the local temperature, pH, salt or water concentration. The material is made from a polymer — a chain made from links of identical units — that have free, water-attracting ends sticking out.

2024年1月24日 · An excellent source for providing moisture to a dry lesion, hydrogel dressings act fast to help cool down a wound, as well as provide temporary relief from pain for up to six hours. Here are a few quick guidelines on when to use hydrogel dressings, its wound healing advantages and also when you should try to abstain from using hydrogel.

In the present review, we focused on the fundamental concepts of hydrogels—classification, the polymers involved, synthesis methods, types of hydrogels, properties, and applications of the hydrogel.

A hydrogel is a network of hydrophilic polymers that are crosslinked either through physical entanglement (reversible hydrogel) or covalent bonds (permanent hydrogel), whilst a gel is a semi-solid material of hydrophilic polymers consisting of large amounts of liquid and small amounts of solids.

2023年5月22日 · Hydrogels are three-dimensional (3D) structured networks of crosslinked hydrophilic polymer matrices capable of holding a large amount of water (> 10%by definition) and displaying useful characteristics such as softness, toughness, biocompatibility, stretchability, and …

2020年7月8日 · In this review, we highlight the highly tunable synthesis of various hydrogels, involving key synthetic elements such as monomer/polymer building blocks, cross-linkers, and functional additives, and discuss how hydrogels can be employed as precursors and templates for architecting three-dimensional frameworks of electrochemically active materials.

Hydrogels are crosslinked polymer chains with three-dimensional (3D) network structures, which can absorb relatively large amounts of fluid. Because of the high water content, soft structure, and porosity of hydrogels, they closely resemble living tissues.

2024年11月4日 · A new way discovered by a team of researchers at the Department of Chemical Sciences in Bose Institute to create hydrogels using tiny protein fragments of just five amino acids from the SARS-CoV-1 virus, could help improve targeted drug delivery & reduce side effects.

2024年12月9日 · Hydrogel is a 3D network of hydrophilic polymer material that quickly absorbs and retains water (or other fluid). As an incredibly versatile and environmentally sensitive material, hydrogel is multi-functional across various industries.
