Hydrogels
overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
Hydrogels are three-dimensional, hydrophilic polymer networks capable of holding large amounts of water while maintaining their structure. They are used across various fields including biomedical applications (such as tissue engineering and drug delivery), agriculture (water-retentive soil additives), and environmental science (contaminant removal). Their unique combination of flexibility, biocompatibility, and high water content makes them versatile materials for numerous innovative uses.
