Hydrogel is a three-dimensional network of hydrophilic polymer chains that can retain a significant amount of water while maintaining their structure. These materials can absorb and hold large quantities of water—sometimes up to several hundred times their dry weight—without dissolving. Due to their high water content, hydrogels exhibit properties similar to natural tissue, making them particularly useful in medical and biological applications.
