Hydrogels are polymeric networks having the ability to absorb a large volume of water. Flexibility, versatility, stimuli-responsive, soft structure are the advantages of hydrogels. It is classified based on its source, preparation, ionic charge, response, crosslinking and physical properties. Hydrogels are used in various fields like agriculture, food industry, biosensor, biomedical, etc. Even though hydrogels are used in various industries, more researches are going in the field of biomedical applications because of its resembles to living tissue, biocompatibility, and biodegradability. Here, we are mainly focused on the commercially available hydrogels used for biomedical applications like wound dressings, contact lenses, cosmetic applications, tissue engineering, and drug delivery.

水凝胶是具有吸收大量水分能力的聚合物网络。柔韧性、多功能性、刺激响应性、结构柔软是水凝胶的优点。它根据其来源、制备方法、离子电荷、响应特性、交联和物理性质进行分类。水凝胶被用于农业、食品工业、生物传感器、生物医学等各个领域。尽管水凝胶在各个行业都有应用，但由于其与活组织相似、具有生物相容性和可生物降解性，生物医学应用领域仍在进行更多的研究。在此，我们主要关注用于生物医学应用的市售水凝胶，如伤口敷料、隐形眼镜、美容应用、组织工程和药物递送。
