Hydrogel

Hydrogel is a soft, jelly-like material made mostly of water and a network of interconnected molecules called polymers. These polymers give the hydrogel its structure, allowing it to hold a large amount of water while remaining flexible and resilient. Hydrogels are used in various applications such as wound dressings, contact lenses, and drug delivery systems because they mimic natural tissues, are biocompatible, and can be engineered to respond to environmental changes. Essentially, hydrogels combine the properties of liquids and solids, providing a versatile platform in medical and technological fields.
